14. 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)

15. 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!

ALP Protection Relay
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

- Set threshold
- Minimum differential
- UnRestrained value
- Slope 1
- Slope 2
- Break point
- Harmonic levels
inrush › 2nd and 4th)
overexcitation › 5th

30. - 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%)
