UK power resistor company Cressall has launched an impulse test centre at its headquarters in Leicester, UK.
The test centre is designed to carry out impulse tests of up to 400,000V. The impulse voltage unit is a 10kJ, four-stage generator with up to 100kV per stage.
The test equipment is used in conjunction with a four channel digital oscilloscope with a sample rate of five GS/s and a nine bit vertical resolution, which helps to produce and save required wave shapes.
According to the loadbank specialist, the company is now able to offer complete testing services to other equipment manufacturers. The in-house test centre is aimed to test specified banks in future designs and potentially reducing cost for the end user. Customers can specify the fault voltage that the equipment must withstand and Cressall can test if the components meet and exceed these demands.
The Leicester-based firm is currently testing a standard high voltage mesh bank construction suitable for 50kV at 70kV per bank at the testing centre.
Cressall manufactures equipment for the use in high voltage applications and safety critical systems in the UK and abroad.
