High Voltage Test Equipment

HZGTU gas-filled non-partial discharge combined electrical test device is suitable for high-voltage, large-capacity GIS, GIL power equipment insulation withstand voltage test, partial discharge test and accuracy test of GIS transformers. It is a necessary device for GIS substations, GIS, GIL power equipment manufacturers, basin insulators, and insulation structural parts manufacturers to conduct preventive tests and factory tests.

Adding a high-voltage casing interface to the equipment can lead to high-voltage, which can perform various high-voltage tests on traditional high-voltage equipment.

The VLF Multifunction Hipot Tester is an advanced electrical testing instrument designed to ensure the safety and reliability of high-voltage electrical equipment. VLF stands for Very Low Frequency, a testing method that uses low-frequency AC voltage, typically around 0.1 Hz, to perform dielectric withstand tests on cables and other electrical components. This technology has become increasingly important in the electrical industry due to its ability to accurately assess insulation integrity without causing damage.

An Impulse Withstand Generator (IWG) is a specialized electrical testing device designed to evaluate the insulation strength of electrical equipment and components under high-voltage conditions. This generator simulates the transient overvoltages that electrical systems may encounter during lightning strikes or switching operations, allowing engineers to assess the durability and reliability of insulation materials.

The AC/DC digital kilovolt meter consists of two main parts: a high-voltage divider and a digital kilovolt meter. The high-voltage divider is a passive resistive-capacitive type, constructed with precision low-temperature drift resistors and high-quality capacitors. The digital kilovolt meter includes a true RMS value circuit, a peak value measuring circuit, and a digital voltmeter. The high-voltage divider is connected to the digital kilovolt meter by a coaxial measuring cable. The high voltage is reduced to a sample value by the voltage divider and is then fed to the digital voltmeter. Using the function selector, the voltmeter can display DC voltage, AC effective (RMS) voltage, AC peak value, and AC peak-to-peak value, offering high measurement accuracy and ease of use.

The intelligent DC high-voltage generator is designed to output negative DC high voltage with excellent voltage stability and high precision. It is an indispensable tool for preventive testing and DC insulation withstand voltage tests. This product is widely used in the preventive testing and scientific research conducted by power generation and power supply departments, power transmission and transformation engineering companies, as well as large factories and mines.

The withstand voltage tester is an instrument applied to measure the density of withstanding voltage. It can visually, accurately, quickly and reliably tests the breakdown voltage, leakage current and other electrical security performance indices of various measured objects, and can act as DC (AC) high voltage power supply to test the performance of components and the complete instrument.

This series of AC and DC high voltage divider is dedicated instrumentation for locale measurements, both high voltage DC measurements, and can measure AC high voltage. The equipment consists of pressure device and measuring instrument is composed of two parts. Divided voltage regulator with balanced equipotential shielding structure, in completely sealed insulating cylinder internal use of high-quality electronic components, and the whole device with accurate testing, good linearity, stable performance, reasonable structure, easy to carry, simple operation, intuitive display characteristics. Therefore, it is an ideal field measurement instrument.
