TDT 12kV Transformer Power Factor Tester

Introduction:

• TDT 12kV Transformer Power Factor Tester is used to measure electrical loss tangent and capacitance of all kinds of high voltage electrical equipment in power plants, substations, laboratory, etc.

• It is composed of a dielectric loss test bridge, a variable frequency power supply, a step-up transformer and a SF6 high stability standard capacitor, it is integrated structure.

• It can also supply high voltage source for testing.

• Frequency can be changed to 50Hz, 47.5Hz\52.5Hz, 45Hz\55Hz, 60Hz, 57.5Hz\62.5Hz, 55Hz\65Hz; 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 test results in the instrument, you can review the results and print it out at any time.

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 full 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 by digital, 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, over current and temperature. The instrument also has the grounding detection function to ensure that no grounding equipment is not allowed to boost.
