Case Study

“Delivering a first-class service”

The Task

Power Testing Ltd were requested to attend site at Harrods over a period of weeks during its site high voltage transformer upgrade. This was after a failure of a new transformer had occurred during energising, leading to the department store opening late for the first time in its 183 year history. Power Testing Ltd recommended high voltage testing sequences and procedures to confirm the new equipment integrity prior to energising.
