Automatic Transformer Tan Delta Tester, Power Factor Tester -- Model TDT
Introduction:
- TDT Transformer Tan Delta Tester is a high-precision instrument, which can be applied to measure electrical loss tangent and capacitance of all kinds of high voltage electrical equipment in power plants, substations, laboratory, etc.
- TDT Transformer Power Factor Tester 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;
- TDT can also supply high voltage source 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, super touch interface, each process is very clear, the operator does not need additional professional training can be used. It is a ideal intelligent equipment for measuring dielectric loss.
Mass storage data
The instrument is equipped with a calendar chip and large capacity memory, the test results can be stored, you can review the results at any time, and can print it out.
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 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. The instrument can also test the CVT ratio and voltage angle difference.
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. The instrument also has the grounding detection function to ensure that no grounding equipment is not allowed to boost.
