HTJS-H Capacitance & Tan-delta Tester

Brief introduction Dielectric Loss Measurement is very basic insulation testing method which can effectively found the deterioration damp deterioration of electrical equipment insulation, as well as local defects. In electrical manufacturing, electrical equipment installation, transfer and preventive tests are widely used. HTJS-H tan delta tester uses variable frequency power supply technology, SCM, and modern electronic technology for automatic frequency conversion, analog / digital conversion and data operations. With strong anti-jamming capability, fast test speed, high precision, easy to operate; switching power supply, 45Hz and 55Hz pure sine wave output, automatic apply voltage, providing a voltage up to 10 kV; automatically filter 50Hz interference, suit forsubstation and other strong electromagnetic interference field testing. Products features  High accuracy. Equipped with standard oil cups and dedicated test lines can realize oil dielectric loss measurement.  The tester adopts frequency technology to eliminate the scene 50Hz frequency interference, even under the condition of strong electromagnetic interference, can get reliable data.   Over-current protection, not damage instrument when short circuit or breakdown.   Equipped with standard capacitor and HV power, convenient for field test, lessen field wiring.   Adopts large-screen LCD display, easy to operate.
