The testing of protection equipment schemes presents a number of problems. This is because the main function of protection equipment is solely concerned with operation under system fault conditions, and cannot readily be tested under normal system operating conditions.
This situation is aggravated by the increasing complexity of protection schemes and use of relays containing software. Global Power Test has the state-of-art equipment, DOBLE F615, from DOBLE Engineering, to thwart the complexity involved
The testing of protection equipment may be divided into four stages:
- Type Tests
- Routine Factory Production Tests
- Commissioning Tests
- Periodic Maintenance Tests
