High voltage cable fault testing and diagnostics

High voltage cable testing is practically synonymous with informed life management of an asset owner’s cable infrastructure. A consistent regimen of analysis and reporting significantly improves a utility’s reliability indices. Megger offers cable testing solutions for cable fault location and cable diagnostics, as a packaged cable test van and for telecom/datacom assessment.

Circuit breaker analyser and test systems

Circuit Breakers are the metaphorical “safety-valves” of electrical systems; a means of giving harmless vent to excessive energy in a circuit, thereby minimizing the risk of damage to equipment that would otherwise be subjected to non-design conditions. Various power system components depend on the proper operation of a circuit breaker including, for example, expensive power transformers (e.g., in the case of HV and MV circuit breakers) or critical processes in a nuclear power plant (as in the case of LV moulded case breakers).

Current and voltage transformer testing

The need for a comprehensive current transformer testing regime is evident when the alternative is considered: a catastrophically damaging current transformer fault. A fault leading to an open secondary could cause the primary current to overwhelm the insulation, causing the winding to short circuit. Megger’s range of current transformer test equipment allows you to construct an in depth test and maintenance programmed to prevent problems before they occur.

A routine series of diagnostics and testing for your current transformer should include CT saturation testing to identify the knee point against IEEE or IEC standards, CT ratio tests to identify that the voltage ratio is within expected parameters and current transformer resistance testing for both the transformer windings and CT insulation resistance testing.
