Product Description

Application
Series Resonant systems with variable inductance result in low power requirements for testing high kVA capacitive loads and this reduces the cost of energy for performing HV tests. This type of system is most widely used for performing AC Withstand tests on all types of capacitive loads and has the added advantage of being well suited for partial discharge measurements and site location. The system is comprised of a variable inductance HV reactance that can be tuned to a given capacitive load to achieve resonance.

Main Advantages

Proven technology for gas insulated switch and power cable testing applications
High Q systems requiring 1/20th to 1/100th of the test power from the mains.
Harmonic Distortion <0.5%.
Minimum fault current as the system detunes during a flashover.
Controlled resonance gives stable output voltage as the voltage is increased or decreased.
System inductor acts as natural PD filter.
Smaller size and weight than conventional transformers or other resonant suppliers.

Modular System Advantages

- Ability to increase voltage and power ratings by adding modules.
- External Air Gap HV protection built in.
- Simple mechanical construction.
- Lighter and smaller than equivalent metal tank style designs or competitors versions.
- More robust mechanical construction than any other supplier.
- Horizontal coil design is mechanically robust.
