Anti-Interference Different Frequency Dielectric Loss Tester
Anti-Interference Different Frequency Dielectric Loss Tester
Brief introduction
JSY- H auto anti-interference dielectric loss tester is a high precision instrument which the power plant and substation use to automatically measure the dielectric loss targent and capacitance of high voltage electric power equipment in field. Use inverter technology to ensure the accurate measurement under strong electric field interference.
Product features
◆Use inverter technology to ensure the accurate measurement under strong electric field interference.
◆With positive and negative connecting modes measure ground or not ground high voltage electrical equipment. Also can measure the capacitance voltage transformer tgδand the main capacitor C1、C2 capacitance.
◆Equiped with high voltage boosting transformer with protection measurement of zero switch, lightning protection ect.
◆Can take measurement for CVT transformer.
