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.

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 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.

what is the main purpose of high voltage tester ?

The main purpose of a high voltage tester is to verify whether the insulation of electrical equipment can withstand high voltage without breakdown or leakage.
It ensures operational safety and helps prevent electric shock, short circuits, and other electrical failures.

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.

Can your tester be used for onsite testing or only for laboratory applications?

Our high voltage testers are suitable for both onsite field testing and laboratory applications.
We offer portable, lightweight,which are ideal for field use—especially in cable testing, transformer testing, and GIS testing.
For high-precision or large-capacity testing in a controlled environment, we also provide ab-type systems with enhanced functionality and higher test capacity.

What are the main differences between DC hipot, power frequency AC, and VLF testers?

DC hipot testers apply direct current and are mainly used for testing cables and arresters but may not reflect real operating conditions.
Power frequency AC testers use 50/60Hz output and are ideal for simulating actual service conditions, commonly used in transformers and GIS.
VLF testers operate at very low frequencies like 0.1Hz and are suitable for testing medium-voltage cables with low power consumption.
Each type serves different applications based on insulation material, equipment type, and field or lab use.
