AC Test Transformer System

PowerHV supply AC test transformer system up to 2250kV which are especially designed for testing high voltage products and components, such as cables, power transformers, gas-insulated switchgears, bushings and arresters. It is also suitable to test insulation materials. They are used to generate testing high voltage and function as part of the complete system. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (inductive voltage transformers).

PowerHV also supply SF6 insulated test transformer which is designed as a Gas-insulated model which convenient for testing GIS/GIL components and switchgears. This makes testing of such installations possible without feeding them through an air-SF6 bushing.
