1.Overview
HZGS-206A Automatic dielectric loss tester is the high accuracy measuring instrument for power station,transformer substation etc.field or laboratory to test the high voltage electric power equipment dielectric tangent value and capacitance.it is integrated structure,there are dielectric loss test inside,with frequency conversion voltage power source,boosting transformer and SF6 high stability standard capacity.The test high-voltage power supply is generated by the inverter inside the instrument,and used to the test product after boost by transformer.The frequency can be changed to 45Hz or 55Hz,55Hz or 65Hz,47.5 or 52.5HZ,adopt digital trapping technique,it avoids the interference of power frequency electric field to the test,Solving the problem of accurate measurement under strong electric field.It also suit for the blackout situation of generator power supply inspection testing.
2.Product Features:
1.1,Touch large LCD display
1.2,mass storage date
With calendar chip and mass storage inside,you can save the test result in chronological order,view the history records any time and can be printed.
1.3,advance date management
The instrument date can be exported through U disk,you can view and manage the date in any PC machine through our company special software.
1.4,variety test mode
It can tested in variety ways,such as positive connection,opposition method,CVT self-excitation.
1.5, without disconnecting high tension leads measurement the CVT.
The instrument can accurately measure CVT dielectric loss and capacitance without disconnecting CVT high tension leads.
1.6, CVT anti-grafting method is used to measure C0
The instrument can be used to measure the dielectric loss value and capacitance value of CVT.
1.7,high speed sampled signal
The inverter and the sampling circuit in the instrument are all controlled by digital and the output voltage is continuously adjustable.
1.8,multi protection safe and reliable
The instrument have multi safeguard procedures, such as input voltage variations,output short circuit,over-voltage,over-current,temperature,
The instrument also has a grounding detection function to ensure that the non-grounding device is not allowed to boost.
