TDT Transformer Tangent Delta Testing 10kV 12kV Transformer Tan Delta Tester
Introduction:
- TDT Transformer Tan Delta Tester is used to measure electrical loss tangent ( ) and capacitance of all kinds of high voltage electrical equipment in power plants, substations, laboratories, etc.
- TDT Transformer Tan Delta Tester is composed of a dielectric loss test bridge, a variable frequency power supply, a step-up transformer, and an SF6 high stability standard capacitor, it is an integrated structure.
- TDT Transformer Tan Delta Tester can also supply high-voltage sources for testing.
- Frequency can be changed to 50Hz, 47.5Hz52.5Hz, 45Hz55Hz, 60Hz, 57.5Hz62.5Hz, 55Hz65Hz; thus, it can avoid interference of power frequency.

Features:
- Large LCD display: Equipped with a high-end full-touch LCD screen.
- Mass storage data: It can save 200 groups of test results in the instrument.
- Multiple test modes: The instrument has high pressure, high voltage, standard, positive connection method and reverse connection method, self-excitation method, and other methods as optional; high voltage in standard high voltage conditions (greater than 10kV) dielectric loss.
- CVT test: The instrument can also test the fully sealed CVT (capacitor voltage transformer) C1, C2 dielectric loss and capacitance, to achieve the C1, C2 simultaneous test. The instrument can also test the CVT ratio and voltage angle difference. It can accurately measure the dielectric loss and capacitance of CVT without dismantling the CVT high voltage lead.
- High-speed sampling signal: The inverter and sampling circuit of the instrument are all controlled digitally, and the output voltage is adjustable continuously.
- Multi-protection security: The instrument has many protection measures, such as input voltage fluctuation, output short circuit, over-voltage, overcurrent, and temperature. The instrument also has the grounding detection function to ensure that no grounding equipment is not allowed to boost.
