Descripción del producto

Cylinder modular type variable frequency HVAC resonant test systems operate in a frequency range from *0Hz to **0Hz, ideal for field commissioning test of power cables and GIS/GIL according to IEC, and test object is connected to the test system using a flexible high-voltage connection.

The high-voltage reactor is fixed inductance, form resonance with capacitive test load by frequency converter power supply, and provide undistorted sinusoidal AC resonance test power. It features a modular design, oil insulation and cylinder insulated shell. Several reactors can be connected in series or parallel to achieve higher test voltages or power, voltage up to ***0kV.

As part of a series resonant circuit, these systems provide undistorted AC high voltage. And because the systems are designed to have high quality factor (Q), low power is required (1/Q) which results in lower installation and operating costs.

Main applications:

For withstand voltage testing on transformers after they are installed on-site and for purposes of diagnostics in asset management according to IEC ******3.

For withstand voltage tests on XLPE cables once laid on-site (after installation) according to IEC ****0 and IEC ****7.

For testing of withstand voltage at GIS once installed on-site according to IEC ****7 and IEC ********3.
