MEASURING RELAYS AND PROTECTION EQUIPMENT –

Part 11: Voltage dips, short interruptions, variations and ripple on auxiliary power supply port

1 Scope and object

This part of the IEC 60255 series specifies the general requirements for a.c and d.c power supplies, for measuring relays and protection equipment for power system protection, including the control, monitoring and process interface equipment used with those systems This part is based on:

• IEC 61000-4-11 for a.c voltage dips, short interruptions and variations;

• IEC 61000-4-17 for voltage ripple;

• IEC 61000-4-29 for d.c voltage dips, short interruptions and variations

The objective of the tests is to confirm that the equipment under test will operate correctly when energised and subjected to dips, interruptions and alternating components (ripple) The requirements specified in this standard are applicable to measuring relays and protection equipment in a new condition and all tests specified are type tests only

The object of this standard is to state:

• definitions of terms used;

• test severity levels;

• test equipment;

• test set-up;

• test procedure;

• criteria for acceptance;

• test report

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply

3.1

type test

conformity test made on one or more items representative of the production

[IEV 151-16-16]

3.2

equipment under test

EUT

equipment which may be either a measuring relay or a protection equipment

3.3

auxiliary power supply port

AC or d.c auxiliary energising input of the EUT

NOTE Ports connected to voltage transformer (VT) or current transformer (CT) are not covered by this standard.

3.4

alternating component

Ac

alternating component in d.c is defined as:

0

min max

U

U

U −

=

where

Umax= maximum instantaneous voltage;

Umin = minimum instantaneous voltage;

U0 = d.c component

[IEV 161-02-26, modified]

4 Requirements

It is important that the effects of the tests should be assessed at the maximum and minimum values of the voltage according to the product technical documentation

The voltages in this standard use the rated voltage for the equipment (UT) as a basis for voltage test level specification Where the equipment has a rated voltage range, the test procedure shall be applied for both the lowest and highest voltages declared in the voltage range

EXAMPLE A product with a rated voltage range of 100 V to 200 V ± 20 % should be tested at 80 V and 240 V.

Products shall be tested as described in Table 1 For products intended to be powered by d.c power supply, only the corresponding tests shall be done For products intended to be powered by a.c power supply, only the corresponding tests shall be done For products intended to be powered either by a.c power supply or by d.c power supply, both tests shall

be done
