GOZ-JSC Pilot Frequency Dielectric Loss Tester
GOZ-JSC pilot frequency dielectric loss tester is used in power plants, substations and laboratories to test various high voltage electrical equipment dielectric loss tangent and capacity with high-precision. Instrument is the integration of structure, with built-in dielectric loss test bridge to regulate power supply by variable frequency boost transformer and SF6 high stable standard capacitor. GOZ Technology can meet requirements like China State Grid Electricity Power Research Institute and other relevant authorities inspection, and issue SF6 online monitoring system test report.
Also called: Dielectric Loss Tester, Anti-interference Dielectric Tester, Auto Dielectric Loss Tester, Pilot Frequency Dielectric Tester, Pilot Frequency Dielectric Loss Tester, Anti-interference Dielectric Loss Tester
1.
Large LCD Chinese display
Instrument is equipped with a large screen (105mm × 65mm), which is divided into two parts, left of the function menu area and right of the relevant status information. Each step is very clear, so the operator does not need to be trained with professional knowledge. One operation, computer automatically completes the entire measuring process, which is ideal dielectric loss measurement equipment.
2. Mass storage data
Instrument is equipped with a calendar and a large-capacity memory chip, which can save the test results in chronological order, so you can view print out whenever.
3. Science and advanced data management
Instrument data can be exported via U-disk, and you can check, manage and generate work report in any PC through our special software.
4. A variety of test mode
Instruments uses the internal & external high pressure, internal & external standard, positive & reverse connection, and self-excitation method to test; under external high pressure, high voltage dielectric loss can be done (greater than 10kV).
5. One step CVT test
The instrument can also test the whole sealed CVT (capacitor voltage transformer) dielectric loss and electrical capacity with C1, C2 at the same time.It can also test the CVT ratio and voltage angle difference.
6. High-speed sampling signal
Inverter inside and sampling circuit are all digital controlled, and the output voltage is continuously adjustable
7. Multiple protection safe and reliable
Instrument has input voltage fluctuation, output short circuit, over voltage, over current, temperature and other multiple protection measures to ensure the equipment safe and reliable. It also has ground fault detection function to forbid boost voltage without ground.
