The HVTTD12B Transformer Dielectric Loss Tangent Delta Tester is an instrument specially designed for testing the capacity of standard distribution power transformers under lower voltage and lower currents.
Dielectric loss or dissipation factor measurement is a good method as part of the insulation test, which can effectively find the overall moisture deterioration and deterioration of electrical equipment insulation, as well as local defects.
It is widely used in electrical engineering, electrical equipment installation, handover and preventive testing. The measurement of dielectric loss of transformers, transformers, reactors, capacitors, bushings, arresters, etc. is the most basic method to measure the insulation performance.
The instrument uses Fourier transform digital filtering technology to measure capacitance, dielectric loss and other parameters. The precision of the test results is ideal for automatic measurements.
Frequency conversion technology eliminates 50Hz power frequency interference in the field, and even in an environment of strong electromagnetic interference.
Use full-touch super large LCD, easy to operate.
Data storage: save the test results and results can be displayed and printed at any time.
Data can be exported to Flash.
Data can be viewed and managed by PC software
Equipped with thermal printer for printing and output and USB port for a Flash disk
Easy to operate. When a selected measurement method is selected, the data measurement can be completed automatically.
Integrated model, with standard capacitor and highvoltage power supply, facilitates field testing and reduces field wiring.
Due to the high measurement accuracy of the instrument, the requirements of oil dielectric loss measurement. can also be performed by equipping the standard oil cup
It has a reverse wiring low-voltage shielding function. When the 220kV CVT bus is grounded, 12kV reverse wiring dielectric loss measurement can be performed on the C11 without removing the wires.
Able to do an AC withstand test. It is useful for PT, CT secondary side ac withstand voltage, 400V low-voltage system to do the withstand voltage test.
