Testing and Commissioning

Our high voltage power engineers are well equipped to test and commission all the equipment within your electrical transmission and distribution infrastructure.

Cables are subject to damage; we can carry out a series of tests to identify and locate the fault, then carry out the necessary repairs as required.

Transformer testing is crucial for mitigating the risk of operating failure.

Due to its static nature, the power transformer can be regarded as a very reliable unit. Nevertheless, there is a possibility of failure because of internal faults as well as being subjected to stresses from external sources which could cause an internal fault condition.

Advanced Cabling Contractors offer Earthing Studies, HV Grading Studies and HV Protection Testing Studies.

We will determine the required settings to ensure that your equipment has the right protection settings. That way any fault is managed correctly and power distribution assets will be safe during use and if a fault occurs.
