Automatic Transformer Tangent Delta Power Factor Tester Electrical Instrument

Capacitance Tangent Delta Power Factor Dielectric Loss Tester

I.Introduction:

Tangent delta tester is a high-precision instrument, which can be applied to automatically measure electrical loss tangent ( ) and capacitance of all kinds of high voltage electrical equipments on the spot of power plants, substations,laboratory, etc. The instrument is an integrated structure with a dielectric loss test bridge, a variable frequency power supply, a step-up transformer and a SF6 high stability standard capacitor.

II.Features:

★Large LCD display

Simple operation, the instrument is equipped with a high-end full touch LCD screen, super touch interface, and each process is very clear. Operators can use it without additional professional training.

★Mass storage data

The instrument is equipped with a calendar chip and large capacity memory. The test results can be stored in chronological order. Users can view historical data at any time and print it out.

★Multiple test modes

The instrument can be tested by high pressure, high voltage, standard, positive connection method, reverse connection method, self excitation method and other methods.

★CVT test step in place

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.

★Do not dismantle the high-voltage lead measurement CVT

The instrument can accurately measure the dielectric loss and capacitance of CVT without dismantling the CVT high voltage lead.

★CVT reverse shield method for measuring C0

The instrument can be used to measure the dielectric loss and capacitance value of C0 on the upper end of CVT.

★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.
