AJS-VI Different Frequency Dielectric Loss Tester

Estimated delivery : 45 Days; MOQ : 1 PCS
Product Introduction Overview :
The frequency-variable automatic dielectric loss tester is a high-precision test instrument for testing the dielectric loss tangent value and capacitance of various high-voltage power equipment on-site or in laboratories such as power plants and substations. The instrument is an integrated structure with a 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 inverter inside the instrument and is used for testing the test product after being stepped up by the transformer. The frequency can be changed to 50Hz, 47.5Hz\52.5Hz, 45Hz\55Hz, 60Hz, 57.5Hz\62.5Hz, 55Hz\65Hz. The digital notch technology is used to avoid the interference of the 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 the generator is used for power supply detection after all power outages. The instrument is equipped with an insulating oil cup and a temperature control device to test the dielectric loss of insulating oil.

Features :
Large LCD Chinese display
The operation is simple. The instrument is equipped with a high-end full-touch LCD screen and a large full-touch operation interface. Each process is very clear and the operator can use it without additional professional training. The entire process can be completed with just one click. It is currently an ideal intelligent dielectric loss measurement device.
Massive storage of data
The instrument is equipped with a calendar chip and a large-capacity memory, which can store 200 sets of data. The test results can be saved in chronological order, and the historical records can be viewed at any time and printed out.
Scientific and advanced data management
The instrument data can be exported via a USB flash drive and can be viewed and managed on any PC using our company's dedicated software.
Multiple test modes
The instrument can be tested using multiple methods including internal high voltage, external high voltage, internal standard, external standard, positive connection, reverse connection, self-excitation, etc.; high voltage (greater than 10kV) dielectric loss can be tested under external standard and external high voltage conditions.
CVT testing in one step
The instrument can also test the dielectric loss and capacitance of the fully sealed CVT (capacitive voltage transformer) C1, C2, and realize the simultaneous testing of C1 and C2. The instrument can also test the CVT ratio and voltage angle difference.
Measuring CVT without removing high voltage leads
The instrument can correctly measure the dielectric loss and capacitance 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 shielding 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, 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., which ensure the safety and reliability of the instrument. The instrument also has a grounding detection function to ensure that ungrounded equipment is not allowed to increase voltage.
