Dielectric loss tester can effectively find the overall damp, deterioration and partly defects of electrical equipment insulation, which are widely used in electrical manufacturing, electrical equipment installation, handover and preventive testing.
The anti-interference precision dielectric loss tester is used for on-site anti-interference, dielectric loss measurement or laboratory dielectric loss measurement. The instrument is an integrated structure with built-in dielectric loss bridge, variable variable frequency power supply, test transformer and standard capacitor, etc.. The instrument adopts frequency conversion anti-interference and Fourier transform digital filtering technology, fully automatic and intelligent measurement, and the measurement data is very stable under strong interference. The result of measurement is displayed by large screen display, and the instrument comes with micro printer to print and print test results.
High voltage protection: Under condition of short circuit, breakdown or high voltage current fluctuation, it can cut off output at a high speed by short circuit mode
Power supply protection: incorrect connection of 380V, power supply fluctuation or sudden power failure, it will starti protection and avoid to cause over-voltage
Ground protection: it has the function of ground wiring detection and can not step up when it is not grounded. If the instrument is not grounded properly, the ground protection is started
CVT protection: four protection limits of voltage and current in high voltage, voltage and voltage and current in low voltage side to protect the equipment; the wrong menu will not output the exciting voltage. In CVT measurement without 10kV high voltage output
Anti misoperation: two level power switch; real-time monitoring of voltage and current; repeated key confirmation; distinctive terminal of high/low voltage; slow step-up; quick decompression; sound and light alarm
Anti-"Capacitance rise": when measuring large capacitance sample, the "rise" effect of voltage can occur. The instrument can automatically track the output voltage and keep the test voltage constant
High voltage cable: high voltage insulated wire can be used even connectting the floor
Anti-seismic performance: the instrument adopts unique anti-seismic design, and can withstand strong long-distance transportation, vibration and jolt without damage
