Product Introduction: High Voltage Switch Mechanical Characteristics Tester is a five-level maintenance and testing tool, which is a high-precision testing instrument used in power plants, substations and other field or laboratory settings to test the dielectric loss tangent and capacitance of various high-voltage power equipment. The instrument adopts an integrated structure, built-in dielectric loss test bridge, variable frequency voltage regulating power supply, step-up transformer and SF6 high stability standard capacitor. The test high-voltage source is generated by the internal inverter of the instrument, and after being boosted by the transformer, it is used for testing the test object. The frequency can be changed to 45Hz or 55Hz, 55Hz or 65Hz, using digital notch technology to avoid the interference of power frequency electric field on the test, fundamentally solving the problem of accurate measurement under strong electric field interference. It is also suitable for occasions where power is supplied by generator after complete power outage.

Main Features:
1. Large LCD Chinese Display
Equipped with a large screen (105mm×65mm) Chinese menu interface, the screen display is divided into left and right parts, the left side is the function menu area, the right side is the relevant status information prompt, each step is very clear, operators can use it without professional training. One operation, the microcomputer automatically completes the whole measurement process, it is currently a very ideal dielectric loss measurement device.
2. Massive Data Storage
The instrument is equipped with a calendar chip and large capacity memory, can save the test results in chronological order, can view historical records at any time, and can print output;
3. Scientific and Advanced Data Management
The instrument data can be exported through U disk, can be viewed and managed on any PC through our company's dedicated software, and can generate work reports.
4. Multiple Test Modes
The instrument can use internal high voltage, external high voltage, internal standard, external standard, positive connection method, reverse connection method, self-excitation method and other methods for testing; under external standard and external high voltage, high voltage (greater than 10kV) dielectric loss can be tested.
5. CVT Test in One Step
The instrument can also test the dielectric loss and capacitance of fully sealed CVT (capacitive voltage transformer) C1, C2, realizing simultaneous testing of C1 and C2. The instrument can also test CVT ratio and voltage angle difference.
6. High-Speed Sampling Signal
The inverter and sampling circuit inside the instrument are all digitally controlled, and the output voltage is continuously adjustable.
7. Multiple Protection, Safe and Reliable
The instrument has multiple protection measures such as input voltage fluctuation, output short circuit, overvoltage, overcurrent, temperature, etc., ensuring the safety and reliability of the instrument. The instrument also has a grounding detection function to ensure that ungrounded equipment is not allowed to boost voltage.
