Product Introduction
Measuring dielectric Loss is a basic method in insulation tests, which can effectively find the deterioration damp of insulators on electrical equipment as well as local defects. It is widely used in electrical manufacturing, electrical equipment installation, handover, and preventive tests. It is the most basic way to evaluate the insulation of electric equipment by measuring the dielectric losses of its transformers, instrument transformers, reactors, capacitors, bushing, and arresters.

Product Feature And Application
1. Big touched screen LCD display: easy to use and no need to train the user, only click the screen to finish the whole test process
2. High storage capacity: can save 200 group data, results can be saved in chronological order, historical records can be viewed at any time, and can be printed out;
3. data management: The instrument data can be exported through a U disk, and can be viewed and managed on any PC.
4. Multiple test modes: It can test by internal high voltage, external high voltage, internal standard, external standard, positive connection method, reverse connection method, self-excitation method, and other methods; High voltage (> 10kV) dielectric loss can be made under the condition of external standard external high voltage.
5. CVT test:can test CVT(capacitor voltage transformer)C1/C2 of dielectric loss and capacitance,can test C1/C2 simultaneously. Can also test CVT Variation ratio and voltage Angle difference;
6. no need to remove the high voltage cable to test CVT: can test CVT dielectric loss and capacitance with no need to remove HV cable
7. CVT Reverse connection shielding measuring C0: can test the dielectric loss value and capacitance value of CVT upper C0
8. high-speed sampling signal: The inverter and sampling circuit inside the instrument are all controlled digitally, and the output voltage is continuously adjustable.
9. LCR full auto test: Automatic display inductance, capacitance, resistance measurement, Angle.
10. multiple protection features: such as input voltage fluctuation, high voltage current, output short circuit, power supply fault, overvoltage, overcurrent and temperature, etc., to ensure the safety and reliability of the instrument. also equipped with a grounding detection function to ensure that the ungrounded equipment does not allow voltage boost.
