High Voltage Testing Of Power System Equipment

High voltage withstand tests are used in conjunction with partial discharge measurements on solid dielectric cable and accessories within manufacturing plants to ensure the quality of completed cable system components from mv to ehv.

High voltage testing of power system equipment.

Test results are delivered automatically and include scope traces of dynamic resistance and noise. These recommended practices deal generally with safety in connection with testing in laboratories in the field and of systems incorporating high voltage power supplies etc. Low voltage systems less than 1 000 volts medium voltage systems greater than 1 000 volts and less than 100 000 volts high voltage and extra high voltage systems greater than 100 kv and less than 1 000 kv description. Equipment and conductors that carry high voltage warrant special safety requirements and procedures.

Normally the design of the laboratories for 230 kv system voltage and below does not pose any problems but laboratories intended for system voltages of 400 kv and above require special attention. High voltage is used in electrical power distribution in cathode ray tubes to generate x rays and particle beams to. Contact us at 855 459 4377 we are ready to service your immediate needs. Mk test systems are used to test dynamic resistance of the contacts throughout rotation resistance noise throughout rotation and high voltage isolation between rings.

Our equipment is based on an understanding of all of the technological milestones of the last 100 years and follows a new approach to hv testing solutions. Laboratories depends on the test facilities to be provided. Evergreen high voltage is a new company formed by experienced long time industry participants which will transform our customer s experience in purchasing high voltage testing systems. Our services include performance testing dielectric testing r d testing failure analysis and accident recreation.

Bulk power transmission can be most efficiently done through high voltage electrical power transmission system hence high voltage system becomes most essential requirement for power transmission. The high voltage laboratory rating and size of test equipment chosen in the h v. Three voltage classes of equipment are detailed within the ansi neta ecs. Iti possesses the latest equipment in voltage and current testing that spans up to 120 000 volts and 40 000 amps.

The electrical power demand is rising rapidly. For the purposes of these recommended practices a voltage of approximately 1 000 volts has been assumed as a practical minimum for these types of tests. In certain industries high voltage refers to voltage above a certain threshold. Thus it is quite natural for utilities to also use withstand and partial discharge tests as commissioning and maintenance tests for cable.

Electric power systems is an essential service provider and we are open for business during the covid 19 pandemic.
