Channel Check Mode in 1 CPU Mode Without LCD
When the Enter key in the MMI keypad is pressed, or when the shutdown switch (refer to Section 3.7.1 for shutdown information) is pressed for 3 seconds or less (if the shutdown switch is pressed for more than 3 seconds, the device will shut down), the front panel LEDs will display the status of the analog channels.
The nine LEDs on the front panel display the status of the first nine analog channels as shown in the following table (9 LEDs and 9 analog channels are mapped one-to-one; LED 1 indicates the status of Channel 1, LED 2 indicates the status of Channel 2, and so on).
LED Status Channel State Description
Off Channel is not measuring. Amplitude is less than 10% of the nominal voltage.
Green Channel is measuring. Amplitude is in between 10% and 120%
of the nominal voltage and the phase sequence is proper.
Amber Phase error in the Channel Phase sequence is not proper.
Red Channel is saturated. Amplitude is greater than 120% of the nominal voltage.
The Channel Check mode is terminated and moved to the default state when:
• The Enter key is pressed, or
• After 5 minutes (fixed length timeout).
Channel Check Mode in 1 CPU Mode with LCD and 2 CPU Modes
The user can select the Channel Check mode menu option by using the LCD and the keypad (refer to Figure 3.20).
In this mode, the user can observe the sub menu options as:
• Analog Inputs
• Digital Inputs
The Analog Inputs Check screen is editable for changing the channel numbers using the up and down arrow keys. The screen displays the RMS magnitude and transformer ratio of the selected channel. Alarm LEDs represent the phase error status of the selected channel.
For example, suppose Channel 1 is configured as phase A, Channel 2 is configured as phase B, and Channel 3 is configured as phase C. If the user selects Channel 1, and if any phase error occurs, then alarm LED will glow Red. For details, refer to the LED 6 indication provided in the table in Section 3.6.6.
For standalone, the Phase error indication is not applicable.
The Digital inputs screen displays the state of the 64 digital channels. The user has to scroll using the up and down arrow keys to check the state of all the 64 channels.
3.7. Shutdown and Reset
Pressing the reset or the shutdown switch when the device is running may lead to the loss of data that is under acquisition. However, the data that is already available in the device will not be affected.
3.7.1. Shutdown Switch
The INFORMA PMD-A device can be shut down gracefully by pressing the shutdown switch for more than 3 seconds. After the device shuts down, the Healthy LED (on the front panel of the device) stops glowing, indicating a successful shutdown. Now, the user can switch off the power supply to the device.
Switching off the device without a graceful shutdown might corrupt the memory device.

3.9. USB
3.9.1. USB Functionality
When a user plugs in a USB storage device to INFORMA PMD-A, the device checks for a specific folder and validates the unique serial number and digital signature available in the script file inside the folder. Once the digital signature is verified, the INFORMA PMD-A device parses the script file to perform any of the following operations:
• Upload and download configuration
• Firmware upload
• Data download
In addition, the user can select and download data to the USB through the MMI.

Figure 3.27 – USB LED Indication
3.10. Clock Synchronization
Each INFORMA PMD-A device has an internal clock for maintaining the time-stamp for recorded data. This clock can be synchronized to an external GPS, internal RTC, IRIG-B, or IRIG-J. When multiple INFORMA PMD-A devices are installed at any one site, any one device (the time master) can be used to synchronize the other devices (time slaves) by using a PPS signal (Refer to Figure 4.2).
Therefore, using clock synchronization, all INFORMA PMD-A devices can be synchronized to the same time and synchronously sampled to the GPS, internal RTC, IRIG-B, or IRIG-J.
3.10.1. INFORMA PMD-A as Master Using an External GPS PPS
An external GPS antenna shall be connected to the BNC connector on the rear panel of the INFORMA PMD-A device.
The antenna cable type is RG6 with BNC terminations connected to a Trimble Bullet antenna (maximum length is 45 m without an amplifier).
Using Internal RTC
INFORMA PMD-A can be configured to use its internal RTC as the time reference.
When INFORMA PMD-A uses internal RTC as a time reference for its operation, the external substation pulses of PPM or PPH correct any drift in the RTC time. Alternatively,
INFORMA PMD-A can be configured to generate an internal PPH signal by counting the 50/60 Hz line frequency signal from a configured FR Frequency reference voltage channel.
Internal PPH signal should only be used when the line frequency has a tolerance of 0.06%. This would typically be used to eliminate a long-term drift in the internal RTC time when an external time reference is not available.
If the frequency in the selected voltage channel is beyond 0.06% tolerance, the device will experience frequent “Abrupt Time Shifts”.
If the amplitude in the selected voltage channel is below 10% of nominal voltage, the device will experience frequent “Abrupt Time Shifts”.
External PPH signal is validated only if it is within ±5 minutes of an hour boundary as determined by RTC time. If the PPH signal is received beyond this ±5-minute time window, it is rejected and no actions are performed. Therefore, a user must initially set the time on the INFORMA PMD-A device to an accuracy of 5 minutes while using the external PPH.
External PPM signal is validated only if it is within ±10 seconds of a minute boundary as determined by RTC time. If the PPM signal is received beyond this
±10-second time window, it is rejected and no actions are performed. Therefore, a user must initially set the time on the INFORMA PMD-A device to an accuracy of 10 seconds while using the external PPM.
INFORMA PMD-A can be configured as the time master using iQ+, as shown in the following figure. Refer to iQ+ help for additional information.
Using IRIG-B
INFORMA PMD-A can be configured to use an external IRIG-B time source as the time reference. Connect the IRIG-B cable from the IRIG-B time source to the BNC connector.
INFORMA PMD-A IRIG-B supports the following:
1. IRIG-B 001
Modulation Type : Unmodulated, also called DC level shift.
Frequency/Resolution: No carrier
Coded expression : BCD (does not include year information), CF (includes year information).
2. IRIG-B 121
Modulation Type: Amplitude Modulated Sine Wave Frequency/Resolution: 1000 Hz carrier
Coded expression: BCD (does not include year information), CF (includes year information).
The INFORMA PMD-A device to which the IRIG-B time source is connected will be the time master. This time master INFORMA PMD-A device may now be used to provide time synchronization to other slave INFORMA PMD-A devices, using the differential or Fiber connection for PPS synchronization.
Using IRIG-J
INFORMA PMD-A can be configured to use an external IRIG-J time source as the time reference. Connect the serial cable from the IRIG-J time source to the RS232-2 port.
INFORMA PMD-A IRIG-J supports IRIG-J-14.
IRIG-J-14
The IRIG-J-14 is a Time-of-Year format with a 1-second resolution and frame length. The IRIG-J-14 baud rate is 1200.
The INFORMA PMD-A device to which the IRIG-J time source is connected will be the time master. This time master INFORMA PMD-A device may now be used to provide time synchronization to other slave INFORMA PMD-A devices, using the differential or Fiber connection for PPS synchronization.
3.10.2. INFORMA PMD-A as Slave
When INFORMA PMD-A is configured as a time slave, it receives PPS input from the time master and derives the time of the day by using NTP over the network.
INFORMA PMD-A can be configured as a time slave using iQ+, as shown in the following figure. Refer to iQ+ help for additional information.
For INFORMA PMD-A to be fully time-synchronized as a time slave, both PPS and NTP are required from the time master.
Figure 3.29 – INFORMA PMD-A Time Master/Slave Configuration
Note In the absence of PPS input for the slave mode of operation, INFORMA PMD- A will use NTP time as the time reference from the configured NTP server.
Because INFORMA PMD-A is not synchronized with the PPS time marker, the accuracy of time synchronization is impacted.
3.10.3. INFORMA PMD-A Time Accuracy
Figure 3.30 - INFORMA PMD-A Time Accuracy 3.10.4. PPS Detection, Stability, and Lock Mechanism
INFORMA PMD-A can be configured with any one of the external PPS sources for time reference. Once the edge of the external PPS is detected, the “ON” duration of the PPS pulse is checked, and it must exceed a minimum of 100 ms for the PPS to be validated.
The next level of validation is the “PPS stability check”. The external PPS pulse is said to be stable, as long as the PPS to PPS duration remains constant within the acceptable jitter limit as mentioned in below table.
Sl. No. External Time Source (PPS) Jitter Limit (+/- )
1 GPS 10 µs
2 INT RTC 1 ms
3 IRIG-B 1 ms
4 IRIG-J 1 ms
This check is performed continuously and the status of the PPS stability is updated every 16 seconds. If the external PPS is stable for 16 seconds, then the PPS is declared as stable;
else, it is rejected. When multiple INFORMA PMD-A devices are in the locked state, ADC sampling is synchronized.
INFORMA PMD-A is said to be “locked to External time source” when the internal time is synchronized with the external time source within an acceptable band of time accuracy.
INFORMA PMD-A is said to be in “Not-Locked State” if any of the following conditions occurs:
• The external PPS does not pass the stability check.
• The time difference is not within the acceptable jitter limit.
When there is a transition of INFORMA-PMD-A internal PPS from not-locked to a locked state, time correction occurs. The time correction can happen in any of the following ways:
• Gradual time correction
• Abrupt time shift Gradual Time Correction
The INFORMA-PMD-A internal time is corrected gradually if the difference is less than 0.5 seconds with respect to the external time. The maximum error correction allowed per cycle is approximately half of the intersample delay. Approximately, the time required to perform the correction for a 0.5-second error is 8.5 minutes. As a result, after the device is switched on, the clock synchronization LED might take a maximum of 8.5 minutes to turn on
indicating the system is locked.
Abrupt Time Shift
If the difference in time is greater than 0.5 seconds, then the INFORMA-PMD-A internal time will be abruptly shifted to the external time. The abrupt shift in time is always indicated to the user.
3.11. Analog Inputs
The INFORMA PMD-A 3U device supports 9 analog channels and the INFORMA PMD-A 6U device supports 9/18/27/36 analog channels.
INFORMA PMD-A has the following types of analog inputs:
• TX-AFE
• HIA-AFE 3.11.1. TX-AFE
TX-AFE analog channels have the following characteristics:
• 16-bit resolution for voltage and 20-bit resolution for current
• Phase angle between channels: Accuracy ≤ 0.1°
• Channel Input Impedance of > 2.5 MΩ (at 63 V), > 2 MΩ (at 110 V), 1 MΩ (at 230 V), and > 0.1 MΩ (at 440 V)
3.11.2. HIA-AFE
HIA-AFE analog channels have the following characteristics:
• 24-bit resolution for voltage/current
• Phase angle between channels: Accuracy ≤ 0.1°
• Channel input impedance of 4 MΩ
Refer to Appendix A for details on the technical specifications.
For TX-AFE and HIA-AFE, the range of input of the analog channels is listed in the following table:
Channel Type Nominal Values Full Scale Deflection (FSD) AC Voltage 63.5 V
120 V 240 V 440 V
140 V 270 V 480 V 800 V AC Current 1 A
2 A 5 A 10 A
10 A 20 A 50 A 100 A DC input
Voltages
12 V 120 V 240 V 480 V
Current inputs (4-20) mA current loop External current clamp
Selection of the nominal value is through jumper settings that are available internally to the TX-AFE and HIA-AFE boards. The appropriate FSD of any channel is configured at the factory as per the customer order.
TX-AFE and HIA-AFE support a maximum overload of 1000 V continuous; 3.6 times of nominal voltage (maximum input voltage) for 10 seconds.
Note Wire gauge to be used for TX-AFE and HIA-AFE analog inputs: 12-22 AWG.
All analog channels are calibrated at the factory and there is no need for site calibration.
When there is a combination of current and voltage channels, the user must always ensure that the selected input channel is a current channel before connecting a CT circuit.
Fast Transient Recording (optional)
The fast transient recording card is optional and need to fit in the factory.
• The signals taken from the HIA-AFE channel are processed in order to detect a trigger condition (when the transients occur), and to allow the digital recording of the
waveforms before and after the trigger.
• The transient voltage (up to 6 kV) is detected by the TR module with a bandwidth of 2.5 kHz to 5 MHz.
• Sampling rates (user configurable):
20 MHz
10 MHz
5 MHz
2.5 MHz
1.25 MHz
• TR analog channels have a 12-bit resolution.
3.12. Digital Inputs
The INFORMA PMD-A 3U device supports 32 digital inputs and the INFORMA PMD-A 6U device supports 32/64/96/128 digital inputs. All the input channels are bi-directional.
INFORMA PMD-A supports two voltage levels configured at the factory as per the customer order as shown below.
• For nominal voltage 24 V to a maximum input of 250 V:
o Less than 12 V – No activation
o (12-17) V – Undefined o Above 18 V – Activation
• For nominal voltage 48 V, 110 V, and 220 V, to a maximum input of 250 V:
o Less than 30 V – No activation o (30-35) V – Undefined
o Above 35 V – Activation
The scanning rate of digital inputs is 2 kHz. The minimum pulse width of the digital inputs that can be detected and recorded is greater than 0.5 ms.
The debounce time of digital inputs ranges from 0 to 1000 ms in 1 ms steps.
The purpose of digital inputs is to monitor the state of external contacts normally associated with protection relays and circuit breakers.

Note • The twisted pair Ethernet communications are also known as 10/100 Base-T, and have a maximum range of 100 m (300 ft) under normal conditions for error free communication. It is not recommended that the user extend twisted pair Ethernet cables beyond an adjacent cubicle in a substation environment. This is done to avoid induced transients from other conductors.
• Fiber-optic Ethernet network, also known as 100Base-FX, is recommended for long distance communication that can be extended over 1 km, when being used in multi-mode fiber.
