Agenda

Selectivity (or discrimination)

is a type of coordination of two or

more protective devices in series.

Selectivity is done between

one circuit breaker on the supply side

and one circuit breaker, or more than

one, on the load side.

A is the supply side circuit

breaker (or upstream)

B and C are the load side circuit

breakers (or downstream)



Fast fault elimination



Reduce the stress and prevent damage



Minimize the area and the duration of

power loss

Introduction

Selective coordination among devices

is fundamental for economical and technical reasons

It is studied in order to

:

 rapidly identify the area involved in the problem;

 bound the effects of a fault by excluding just the affected zone of the network;

 preserve the continuity of service and good power quality to the sound parts of the network;

 provide a quick and precise identification of the fault to the personnel in charge of maintenance or to management system, in order to restore the service as rapidly as possible;

 achieve a valid compromise between reliability, simplicity and cost effectiveness.

Main purposes of coordination

The definition of selectivity

“Trip selectivity (for overcurrent) is a coordination between the

operating characteristics of two or more overcurrent protection

devices, so that, when an overcurrent within established limits

occurs, the device destined to operate within those limits trips

whereas the others do not trip”

IEC 60947-1 Standard: “Low voltage equipment

Standards definition

Partial and total selectivity

IEC 60947-2

def. 2.17.2 - 2.17.3

“Partial selectivity is an overcurrent selectivity where, in the presence of two protection devices against overcurrent in series, the load side protection device carries out the protection up to a given level of overcurrent, without making the other device trip.”

B opens only according to fault current lower than a certain current value; values equal or greater than I_s will give the trip of both A and B.

I_s is the ultimate selectivity value! I_s = I_mA

Standards definition

Partial selectivity

Only B trips for every current value lower or equal to the maximum short-circuit current.

“Total selectivity is an overcurrent selectivity where, in the presence of two protection devices against overcurrent in series, the load side protection device carries out the protection without making the other device trip.”

 Other methods are needed to have a total selectivity

 Current selectivity: closer to the power supply the fault point is, higher the fault current is

 In order to guarantee selectivity,

the protections must be set to different values of current thresholds

Current selectivity

Base concept

Here the selectivity is a total selectivity,

because it is guaranteed up to the maximum value of the short-circuit current, 1kA.

Circuit breaker A will be set to a value which does not trip for faults which occur on the load side of B.

(I_3Amin >1kA)

Circuit breaker B will be set to trip for faults which occur on its load side (I_3Bmax < 1kA)

A will be set with the current threshold I₂

Back-up protection

Agenda

Back-up protection (or cascading)

is a type of coordination of two protective

devices in series which is done in electrical

installations where continuous operation is

not an essential requirement.

Back-up protection

What is back-up protection?

Back-up protection

excludes the use

The definition of back-up is given by the

“Back-up is a coordination of two overcurrent protective

devices in series, where the protective device on the supply

side, with or without the assistance of the other protective

device, trips first in order to prevents any excessive stress on

downstream devices”.

IEC 60947-1 Standard: “Low voltage equipment

Part 1: General rules for low voltage equipment”

Back-up protection

Standards definition

IEC 60947-1

def. 2.5.24



Back-up is used by those who need

to contain the plant costs



_{The use of a current-limiting circuit}

breaker on the supply side

permits the installation of lower performance

circuit breakers on the load side



Both the continuity of service and the selectivity are sacrificed

How it works

DOC

Features - Professional and Light Profiles

 DOC can be used with 2 different profiles

 Depending on the user needs and skills it can be recommended to use the Light Profile which hides the advanced and complex features

 DOC Light is for ...

 ... first time, unskilled DOC users

 ... installers – panel builders

who need a simple tool to draw and verify small networks

 DOC Professional is for ...

 ... skilled DOC users

 ... customers working on industrial applications

 ... engineering companies –

OEM‟s looking for a powerful calculation and design tool

 By Macros

 Faster and easier drawing

 Note: it is possible to use Single Objects and Macros independently from the layout

Introduction

Aim of the application Target users Product managed How it works Features Support Tools ASD Assistance How to obtain the software

Features - Single line diagram drawing

 When using the Column layout, Objects are numbered by Page & Column

 All the object in the same feeder have the same number

 I.e: Page =1, Column=3 leads to QF1.3+ WC1.3 +L1.3

Features - MV Diagram Drawing

 The Medium Voltage section of the project can be drawn by the Macros of the typical units of the Unimix switchboard or by Objects for more flexibility

 To pass to the Low Voltage section it is necessary to use the

transformers (when a low voltage section is not needed, the drawing can be completed with MV Loads or Motors)

Introduction

Aim of the application Target users Product managed How it works Features Support Tools ASD Assistance How to obtain the software

Features - Lv Diagram Drawing

 The Low Voltage section of the project can be drawn by the Macros or by Objects for more flexibility

 The Macros available represents the most common Objects

combinations; not available combinations can be realized using the Objects

 1 Macro = 1 Feeder = Many single objects

 I.e.: CB+Cable+Load

 I.e.: Fuse+Cable+Load

 Faster drawing

 Pop-up window

 When drawing a feeder it is possible to insert the main

data making the drawing phase faster
