COMMISSIONING

Powerteam has a very experienced team of commissioning engineers, fully equipped to carry out complete commissioning of a wide range of plant and equipment.

Using state of the art Omicron three phase computerised test injection equipment, our commissioning engineers can set up and test protection schemes ranging from a simple over-current scheme to a six ended digital line differential.

Primary injection and magnetising curve tests of CTs (current transformers) are also handled using computerised automatic testing equipment, producing accurate and repeatable test reports. Transformer ratio, vector group and tap changer tests are also routinely carried out.

Plant testing
Plant testing capability includes on-site SF6 analysis of gas purity, dew point and decomposition products using the latest Dilo equipment, circuit breaker timing tests, reduced voltage trip testing, temperature measurement and calibration.

We also have experience in set-up and commissioning of VF signalling and power line carrier link equipment, and carry a full set of measurement and injection equipment up to 650 kHz

Fibre optic work is covered using optical power meters and visible light injection equipment.

Workshop facilities
Test facilities include our own technical workshop where detailed relay testing can be completed, reducing site time and outage length. Our workshop, based in Belfast, incorporates a full range of relay types, which are used for internal training and development.
