Appendix A – Vip 300

A.1 Introduction

The Vip 300 is a self-powered three phase overcurrent and earth fault protection relay. Protection settings are displayed on the relay front panel (see section A.2) along with manual reset and trip flags.

The CTs are connected to one of two sets of inputs to the relay, to give two different setting current ranges. It is important to ensure that the correct scale label (see section A.3) is in place (either x4 or x2) depending on the inputs and the CT ratio used.

Settings are applied by adjusting the dial selectors to the correct location using a screwdriver. Care should be taken when applying the time settings as the Vip 300 does not use the time multiplier as the time input for IDMT curves (t> or to>). Instead the table on the top right of the front panel should be used to convert the required time multiplier to the Vip 300 setting depending on the IDMT characteristic being applied. For definite time settings (DT, I>>, Io>>) the dials give the relay operating time.

For example, to apply the following typical settings to a Vip 300 relay with 400/1 CTs:

OC 200A VI 0.1TM SEF 32A DT 3s

Looking at the range cards for 400/1 CTs it can be seen that the x2 range provides the option for a phase overcurrent setting (Is) of 200A and an earth fault setting current (Ios) of 32A, the x2 range inputs should be used.

Applying the overcurrent setting:

1. Is should be set to 200.2. I> curve selection should be set to VI.3. t> should be set to 0.3 with a multiplier of x1 (from the table provided this corresponds to

a time multiplier of 0.1).4. As no high set overcurrent is required, I>> should be set to OFF.5. As no high set overcurrent is required, t>> should be set to 0.03.

Applying the earth fault setting:

1. Ios should be set to 32.2. Ios> curve selection should be set to DT.3. DT should be set to 1.4. t> should be set to 0.3 with a multiplier of x10.5. As no high set earth fault is required, Io>> should be set to OFF.6. As no high set earth fault is required, to>> should be set to 0.03.
