Introduction

.

Protection Relays are used to protect equipment from being

damaged by undesired electric phenomenon.

Specific protection functions exists for generators

transformers, transmission line, capacitors, etc..

Various type of functions:

- Instantaneous overcurrent (50) - Undervoltage (27)

- Time overcurrent (51) - Overvoltage (59)

- Over/under frequency (81) - Distance (21)

- Differential (87) - etc…

- Directional Power (32)


Introduction to Protection

.

- Negative sequence can tell how a system is unbalanced

- Zero sequence can tell you about earth fault condition

- Protection relay can add currents to trigger transformer or line

differential protection

- Protection relay can protect from generator overexcitation conditions

(Volt/Hz)

- Infinite possibilities

- Hundred years of evolution in a single box!

Protection function

- Transformer Differential (87)

- Need to protect only transformer zone

Protection function

- Transformer Inrush

- High current created by magnetization of the core

- Harmonic generation (2nd and 4th harmonic monitored)

- Newest transformer have lower losses but are subject to

ultrasaturation

- This leads to lower 2nd harmonic levels (parameter used in

determining inrush conditions)

- You do NOT want to trip in these conditions


Protection function


Protection function

- Set threshold- Minimum differential- UnRestrained value- Slope 1- Slope 2- Break point- Harmonic levels

inrush › 2nd and 4th)overexcitation › 5th

- Set the 87R restrained (harmonic) level

3 modes of operation (for even harmonic level 2nd and 4th )- Restrained

Increase dual slope characteristics in proportion of even

harmonic detected

- TRADITIONAL (for even harmonic level 2nd and 4th )Blocking enabled if harmonic level is greater than set value

(example block above 15%)

- SAFE (for modern transformers)

verify if fundamental is in phase with 2nd harmonic (to validate

this is not a fault). Lower the blocking level (example 8%)
