Omicron CPC 100 All-In-One Test System – Part 8 GIS Systems

Omicron-CPC-100

Gas-insulated switchgears (GIS) are compact and are used in applications where space is limited. For commissioning of GIS a high-voltage (HV) withstand test is required in accordance with standards (IEC 62271-203).

To date the test voltage needed for a withstand test has been produced by a resonance circuit. This test system consists of an HV test transformer, a coupling capacitor and a power control unit. The HV test transformer and the coupling capacitor have to be connected directly to the GIS.

Weak points of this testing principle:

• The complete test system is difficult to transport, because it consists of very heavy and large components.

• It is difficult to use it at test sites with limited space, such as wind turbines.

• The HV test lead must be connected to, and disconnected from, the GIS system for testing. This normally includes a time-consuming venting and refilling process of the SF6 gas.

With the Omicron CPC 100 Multi-functional Primary Test System + CP RC you can perform GIS tests without the need of a big HV transformer. This is possible because the system directly makes use of a specially designed “Power VT” for testing.

This Power VT is an integral part of the GIS and generates the required test voltage. CPC 100 injects power at the low-voltage (LV) side of the VT, producing the necessary voltage on the HV side. As you can directly connect the measuring system to the integrated VT of the GIS system it eliminates the need for draining and refilling any SF6 gas.

The CPC 100 + CP RC system comprises several small and light-weight components (< 21 kg / 46 lbs) which can be transported by one person. With its modular design you can perform GIS tests even at test sites with limited space.

GIS testing

• Withstand test up to 235 kV | max 1.6 nF | with CP RC2

• High-voltage source for partial discharge measurements up to 235 kV | max 1.6 nF | with CP RC2
