Fully Automatic Tan Delta Tester High Precision Anti-interference Dielectric Loss Power Factor Test Set
Product Description
Product overview
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. Measuring dielectric loss of transformers, CT/PT, reactors, capacitors, and bushings, surge arresters and other is the most basic measure of its insulating properties. HTJS-M tan delta tester breaks the traditional bridge measurement method, using variable frequency power supply technology, using 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, automatic digitization, easy to operate; use 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 for substation and other strong electromagnetic interference field testing. Widely used in the power industry transformers, CT/PT, bushings, capacitors, surge arresters and other dielectric loss measurement equipment.

Important Note: On-site transformer housing is generally grounded. When testing the tanδ (dielectric loss) of transformers, the reverse connection method is generally selected. Only for fully insulated transformers is the forward connection method used for testing.
Capacitance Conversion Reference:
1F = 1000mF = 1,000,000,000μF = 1,000,000,000,000pF
1mF = 0.001F = 1000μF = 1,000,000,000pF
1μF = 1,000,000pF = 0.000001F
1F = 1000mF = 1,000,000,000μF = 1,000,000,000,000pF
1mF = 0.001F = 1000μF = 1,000,000,000pF
1μF = 1,000,000pF = 0.000001F
