Impulse Voltage Generator Systems for High-Voltage Insulation Testing

High-voltage electrical equipment may be exposed to transient overvoltages caused by lightning strikes and switching operations. Impulse voltage testing is therefore essential for evaluating insulation strength and verifying the reliability of electrical equipment before it is put into service.

Impulse Voltage Generator

The VERXON Impulse Voltage Generator is designed to generate controlled impulse voltages for the insulation testing of high-voltage electrical equipment. The system supports:

• Lightning impulse voltage tests

• Chopped lightning impulse voltage tests

• Switching impulse voltage tests

• Steep-front voltage tests

These tests simulate different transient voltage stresses and help evaluate the insulation performance of the test object under demanding operating conditions.

Typical Test Objects

The Impulse Voltage Generator can be used for testing a wide range of high-voltage equipment, including:

Power Transformers · Instrument Transformers · GIS/AIS · Power Cables · Bushings · Insulators · Surge Arresters

Different system configurations can be provided according to the required voltage level, energy rating, waveform and test object.

Mobile Impulse Voltage Generator System

For onsite testing applications, VERXON also provides the Mobile Impulse Voltage Generator System. It is designed for lightning impulse, chopped lightning impulse and switching impulse voltage tests at substations, manufacturing facilities and project sites.

The mobile system integrates the impulse voltage generator with the Control & Measurement Syst

em, enabling flexible transportation, efficient onsite setup and rapid deployment. It is particularly suitable for projects where the test object cannot be transported to a laboratory or where onsite acceptance testing is required.

Stationary and Mobile Testing Solutions

Stationary systems are suitable for permanent installation in laboratories and manufacturing facilities, while mobile systems provide greater flexibility for field testing. VERXON can provide customized solutions according to the test requirements, site conditions and technical specifications of each project.

With both stationary and mobile configurations available, VERXON Impulse Voltage Generator Systems provide reliable solutions for high-voltage insulation testing in laboratories, factories and onsite applications.
