Relay protection testing confirms that protection will operate on time and without error during a fault. We test overcurrent and instantaneous overcurrent protection and perform setting and commissioning tests.
When you need it
- Commissioning a new substation or switchgear
- Periodic technical inspections
- False or delayed tripping
- Changes in equipment or load
- After a failure

How we do it
Relay protection and automation testing
01
Review
The protection scheme and settings are checked.
02
Test
Current is injected into relays and breakers; pickup current and time are measured.
03
Setting
Settings are adjusted to design values.
04
Report
Results are recorded in a report.
