clear, the operator can use without additional professional training. At present, it is a very ideal intelligent dielectric loss measuring equipment.
Mass storage data
The instrument is equipped with a calendar chip and a large capacity memory, which can save 200 groups of data, save the test results in chronological order, view the history at any time, and print out.
Scientific and advanced data management
The instrument data can be exported through U disk, and can be viewed and managed on any PC through our company's special software.
Various test modes
The instrument can be tested by internal high voltage, external high voltage, internal standard, external standard, positive connection method, reverse connection method, self excitation method, etc. under external standard external high voltage, it can be used for high voltage (more than 10kV) dielectric loss.
One step CVT test in place
The instrument can also test the dielectric loss and capacitance of the fully sealed CVT (capacitive voltage transformer) C1 and C2, and realize the simultaneous test of C1 and C2. The instrument can also test CVT ratio and voltage angle difference.
CVT measurement without removing the high voltage lead
The instrument can correctly measure the dielectric loss and capacitance of CVT without removing the high voltage lead of CVT.
CVT reverse shielding method for C0 measurement
The instrument can measure the dielectric loss value and capacitance value of C0 at the upper end of CVT by reverse shielding method.
High speed sampling signal
The inverter and sampling circuit inside the instrument are all controlled by digitization, and the output voltage is continuously adjustable.
Multiple protection is safe and reliable
The instrument has multiple protection measures such as input voltage fluctuation, high-voltage current, output short circuit, power failure, over-voltage, over-current, temperature, etc., which ensures the safety and reliability of the instrument. The instrument also has the function of setting grounding detection to ensure that the equipment without grounding is not allowed to boost voltage.
