GIS Switchgear & SF6 RMU.

High Voltage Solution.Com Ltd, wish to announce the release of another new service for detecting Partial Discharge in GIS equipment.

The acoustic emission diagnostic technique is a nonintrusive in-service test used for monitoring acoustic signals produced by partial discharge and loose components. It is specifically designed to detect faults in grounded SF6 gas-insulated systems, such as SF6 filled dead tank circuit breakers.

Advantages:

• Full in-service testing under normal operating conditions.
• Can differentiate between PD, particles, and mechanical defects in SF6 gas insulated systems.

Summary of Existing On Line Partial Discharge Testing Services:
It is now possible to accurately detect PD while the system is in normal service in the following assets.

• GIS / Vacuum / bulk oil substations
• SF6 filled dead tank circuit breakers
• XLPE / Paper lead / oil & nitrogen filled cables
• Power transformer
• Tap Changers
• Voltage Transformers
• Current Transformers
• Capacitor banks
• Generators

For further information about Partial Discharge testing on GIS substations or SF6 filled dead tank circuit breakers such as Ring Main Units, please call Peter Rhodes on +64 2 7419 9952 or .
