Tangent Delta Power Transformer Capacitance Dissipation Dielectric Loss Test Device
I.Description
Dielectric loss measurement is a very basic method in the insulation test, which can effectively find the overall moisture deterioration and deterioration of electrical equipment insulation, as well as local defects. It is widely used in electrical engineering, electrical equipment installation, handover and preventive testing. The measurement of dielectric loss of transformers, transformers, reactors, capacitors, bushings, arresters, etc. is the most basic method to measure the insulation performance. The dielectric loss tester breaks through the traditional bridge measurement method, adopts the frequency conversion power supply technology, uses the single-chip microcomputer, and modern electronic technology to perform automatic frequency conversion, analog-to-digital conversion and data calculation; achieves strong anti-interference ability, fast test speed and high precision. Fully automatic digitalization and easy operation; power supply adopts high-power switching power supply, output 45Hz and 55Hz pure sine wave, automatic pressure, can provide voltage up to 10kV; automatically filter out 50Hz interference, suitable for large electromagnetic interference such as substation testing on the spot. It is widely used in dielectric loss measurement of transformers, transformers, bushings, capacitors, arresters and other equipment in the power industry.
II.Technical Indicators Accuracy: Cx: ± (reading × 1% + 1pF) Tgδ: ± (reading × 1% + 0.00040) Anti-interference index: Frequency conversion anti-interference, can still achieve the above accuracy under 200% interference Capacitance range: Internal high pressure: 3pF ~ 60000pF / 10kV 60pF ~ 1μF / 0.5kV Applied high pressure: 3pF ~ 1.5μF / 10kV 60pF ~ 30μF / 0.5kV Resolution: up to 0.001pF, 4 significant digits Tgδ range: No limit, resolution 0.001%, three kinds of samples of capacitance, inductance and resistance are automatically recognized. Test current range: 10μA ~ 5A Internal high voltage: Set voltage range: 0.5~10kV Maximum output current: 200mA Lifting and lowering mode: The voltage is set freely. For example, 5123V. Test frequency: 40-70Hz single frequency can be set freely. For example, 48.7Hz. 50±0.1Hz to 50±10Hz automatic double conversion random setting. 60±0.1Hz to 60±10Hz automatic double conversion can be set freely.
