High Voltage Testing and Analysis

Ensure Your System’s Safety with Our Reliable High Voltage Testing Solutions.

Electrical devices in substations, power grids, transmission lines or power plants are generally costly to maintain or replace. The best and effectivest way to avoid these expenses is to inspect and maintain equipment on a regular basis. High voltage testing , also known as a dielectric withstand voltage test, is a critical procedure used to assess the electrical insulation of various components such as transformers, motors, cables, HV switches, and other electrical equipment .

High voltage test equipment is applied to performing electrical insulation test for checking insulation level and dielectric strength to assess over voltage capability of electric appliance and insulation material such as transformer, motor, cable, HV switch, generator etc.

Advanced high voltage tester by application

High voltage testers are essential tools in various industries, providing critical insights into the safety and performance of electrical systems. These sophisticated devices are designed to test the insulation and integrity of components and systems operating at high voltages, ensuring they meet stringent safety and reliability standards. Unlike basic electrical testers, high voltage testers are engineered to handle extreme voltage conditions and deliver accurate, reliable results.

High voltage testers work by applying a controlled high voltage to the equipment under test. This process helps identify potential weaknesses, insulation failures, and leakage currents, which could lead to equipment failure or safety hazards. These testers are commonly used across several key fields, each benefiting from their advanced capabilities.

Power Generation and Transmission

In power generation and transmission, high voltage testers are applied to transformers, switchgear, high-voltage cables, circuit breakers, and insulators to ensure their operational integrity and safety under demanding electrical conditions.

Electrical Equipment Manufacturing

In electrical equipment manufacturing, high voltage testers are employed to evaluate the insulation integrity and operational performance of motors, generators, electrical panels, capacitors, and power supplies to ensure safety and reliability in their applications.

Industrial Enterprise Unit

In industrial enterprise uints, high voltage dielectric test equipment are applied to switchgear, circuit breaker to test the dielectric withstand voltage strength to ensure their operational safety .

Calibration Unit

High voltage testers are inportant in measurement and calibration units . They detect whether the insulation materials of electrical equipment have defects, such as cracks or aging, thereby preventing safety hazards like leakage or short circuits during high-voltage operation.

Substation Maintenance

High voltage testers are critical in substation maintenance for assessing the integrity and safety of busbars, surge arresters, disconnectors, and protective relays. They check for insulation failures and potential breakdowns and insulation strength test

Railway electrification

In railway electrification, high voltage testers are utilized to ensure the safety and reliability of critical components, including overhead lines, pantographs, traction transformers, and signaling systems, by assessing their insulation integrity and operational performance under high voltage conditions.

Why do people use VLF Hipot Tester?

VLF hipot testers use a sine wave voltage output that typically ranges from 0.1 Hz to 0.01 Hz. The frequency of the VLF output is important because it affects the test voltage level that can be applied to the insulation without causing damage. At lower frequencies, higher voltages can be applied without damaging the insulation. This is because the low frequency allows the voltage to penetrate the insulation and charge the capacitance of the system, rather than simply causing surface breakdown.

What is the principle of AC resonance test system?

The principle of AC resonance test system is based on the resonant circuit theory. In this test, an AC source is used to excite the system with a specific frequency, and the current response of the system is measured. The test system consists of a variable frequency AC source, a reactor or inductor, a capacitor, and a voltage and current measurement system.

what is withstand voltage test ？

A withstand voltage test is a type of high voltage test that is performed on electrical equipment or systems to assess their ability to withstand a specified voltage level for a certain period of time without breakdown or failure.

The test involves applying a high voltage to the equipment or system under test, typically at a level higher than its rated voltage, for a specified duration. The voltage level and test duration are determined by relevant standards and the specifications of the equipment being tested.
