CP CR500 compensating reactor

Accessory for the CP TD1

The CP CR500 compensating reactor is used together with the CPC 100 multifunctional primary testing system and the CP TD1 for testing the insulation quality of rotating machines, cables and other assets with high capacitances.

For dissipation factor (tan δ) / power factor testing and tip-up testing several CP CR500 units can be connected in parallel. Capacitances of up to 1µF (4 A) can be compensated with 12 kV test voltage and at mains frequency can also be used as high-voltage source to provide compensation of up to 2 µF, for example when performing partial discharge measurements. The frequency can also be varied (15 Hz … 400 Hz) to facilitate optimum compensation during long-time tests.

Advantages

> Portable: compact dimensions and low weight > Flexible: can be used as high-voltage source, as well as for

dissipation factor (tan δ) / power factor testing and tip-up testing

> Extendable: several units can be connected in parallel > Long test times: maximum output duration with optimal compensation by adjusting the frequency

(50 Hz / 60 Hz). The system
