HIGH VOLTAGE TESTS

Type testing is performed on products such as insulators, cables and their accessories, bushings, breakers, GIS, surge arrestors, disconnectors, instrument transformers, capacitors and HVDC valves.

Cable Testing

Various electrical tests are performed on AC and DC transmission cables systems to meet all present needs, including:

• Tests of AC cables according to IEC 60840, IEC 62067 and IEEE 48
• Long term heating cycle voltage tests of AC and DC cable systems
• Electrical type tests for HVDC cables according to Cigré TB 219 or according to Electra 72
• Prequalification testing of AC and DC cables in a controlled environment

PRE-QUALIFICATION TEST OF HVDC AND HVAC CABLES

Different media such as water, soil etc. can be introduced in the test circuit. Requirements such as snaking and ducts can also be introduced into the test circuit.
