Testing & Commissioning
Electrical testing and commissioning of high voltage switchgear and transformers is essential to their safe operation. It is particularly important when energising HV apparatus for the first time, regardless of their size, type or industry. We offer an extensive range of services in terms of switchgear and transformer testing and commissioning. We have been providing such services to the renewable energy sector in Ireland and the UK for 10 years.
Our testing and commissioning services include:
- General and visual checks
- Functional testing of mechanical operations
- Functional testing of electrical operations
- Electrical insulation testing
- Contact resistance testing
- VLF testing
- Protection testing
- Primary injection testing (confirming CT ratios / orientation / relay and circuit breaker tripping)
- Voltage transformer (VT) operation
- Winding resistance measurements
- Transformer protection testing
- Partial discharge testing
- Tan Delta testing
- Post energisation checks
- Fault location, diagnosis and repair
We have vast experience in electrical high voltage testing and commissioning, as you’ll see in the examples below.
