Measurement software

Currently, requirements for software used for impulse measurement are specified in IEC 61083-2. This is the only IEC standard on software in the area of high-voltage test and measurement. However, more and more digital instruments equipped with measurement software are being used in all types of high-voltage tests, including AC and DC tests. These digital measurement systems have many advantages over the traditional analogue systems in that they allow measurement of not only the DC or AC signal, but also other high frequency signals, such as fast voltage changes and transient voltage drops due to pre-discharges in a pollution test. Since software is an important part of a measuring system, systematic testing of software to ensure its reliability and performance is often necessary. In light of this situation, IEC technical committee 42 is currently drafting a new standard on the requirements for software used for DC and AC measurements.

This new standard is likely to be assigned as IEC61083-4

7 CONCLUSION

Significant improvements have been made in the recently revised IEC and IEEE standards for high-voltage and high-current tests and measurements. These improvements reflect the change of industry needs, such as the testing in the UHV range, as well as advancement of technologies, such as digital measurement techniques. A much higher degree of harmonization has also been achieved between the corresponding IEC and IEEE standards, which would no doubt bring benefits to the power industry. Revision of standards is a continuing process. A number of areas that future revision of the standards should consider have also been identified in this document.
