XHJS1000B The dielectric loss tester is a high-precision testing instrument used to test the dielectric loss tangent and capacitance of various high-voltage power equipment on-site or in laboratories such as power plants and substations. The instrument has an integrated structure with built-in dielectric loss test bridge, variable frequency voltage regulator power supply, step-up transformer and SF6 high stability standard capacitor.
The test high-voltage source is generated by the inverter inside the instrument, and is used for testing the tested product after being boosted by the transformer. The frequency can be changed to 50.0Hz, 47.5Hz\52.5Hz, 45.0Hz\55.0Hz, 60.0Hz, 57.5Hz\62.5Hz, 55.0Hz\65.0Hz. It adopts 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 generator power is used for testing after a total power outage.
Large LCD English display
The operation is simple. The instrument is equipped with a high-end full-touch LCD screen and a large-scale touch operation interface. Every process is very clear and clear, and the operator can use it without additional professional training. The measurement of the whole process can be completed with one click, and it is a very ideal intelligent dielectric loss measurement equipment.
Mass storage of data
The instrument is equipped with a calendar chip and a large-capacity memory, which can save 200 groups of data. It can save the test results in chronological order, and you can view the historical records at any time and print out.
Scientifically advanced data management
The instrument data can be exported through the U disk, and the data can be viewed and managed on any PC through our company's special software.
Multiple test modes
The instrument can be tested by various methods such as internal high voltage, external high voltage, internal standard, external standard, positive connection method, reverse connection method, self-excitation method, etc. It can do high voltage (greater than 10kV) dielectric loss in the case of external standard and external high voltage.
CVT test in one step
The instrument can also test the dielectric loss and capacitance of the fully sealed CVT (capacitive voltage transformer) C1 and C2, realizing the simultaneous testing of C1 and C2. The instrument can also test CVT ratio and voltage angle difference.
Measure CVT without removing the high voltage lead
The instrument can correctly measure the dielectric loss value and capacitance value of the CVT without removing the high voltage lead of the CVT.
CVT reverse shielding method to measure C0
The instrument can use the reverse shield method to measure the dielectric loss value and capacitance value of C0 at the upper end of the CVT.
High-speed sampling signal
The inverter and sampling circuit inside the instrument are all digitally controlled, and the output voltage is continuously adjustable.
Multiple protections are safe and reliable
The instrument has multiple protection measures such as input voltage fluctuation, high voltage current, output short circuit, power failure, overvoltage, overcurrent, temperature, etc., to ensure the safety and reliability of the instrument. The instrument also has the function of setting ground detection to ensure that ungrounded equipment is not allowed to boost.
CVT test in one step
The instrument can also test the dielectric loss and capacitance of fully sealed CVT (capacitive voltage transformer) C1 and C2, enabling simultaneous testing of C1 and C2. The instrument can also test CVT transformation ratio and voltage angle difference.
