Product Description

GDGS Transformer Power Factor Tester Tan Delta Tester 

Introduction:
Transformer IPF Power Factor Tester Tan Delta Tester

• GDGS Automatic Transformer Power Factor Tester, Transformer Tan Delta Tester is an integrated structure, there is a dielectric loss test bridge, a variable frequency power supply, a step-up transformer and a SF6 high stability standard capacitor built-in;

• 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;

• It can also use generator as power supply;

• If equipped with a insulation oil vessel and a temperature detector, it can also measure tan delta of insulation oil;

Working Principle:
Transformer IPF Power Factor Tester Tan Delta Tester
 

• In the AC voltage, the dielectric to consume part of the energy, this part of the energy will be converted to heat energy loss. This energy loss is called dielectric loss.
• When AC voltage is applied on the dielectric, the dielectric between voltage and current in phase difference angle psi, delta psi is called the dielectric loss angle tangent TG delta delta is called dielectric loss tangent. TG delta value is used to measure dielectric loss parameters. The instrument measuring circuit includes a standard circuit (Cn) and a test loop (Cx), as shown in Figure 2 - 1. The standard circuit is composed of a built-in high stability standard capacitor and a measuring circuit. Measurement line sampling resistor with pre amplifier and A/D converter. By measuring circuit are respectively measured by standard test and loop current loop current amplitude and phase difference, then the digital signal processor using digital real-time acquisition method, obtained through vector operation test of capacitance and dielectric loss tangent value. The anti-interference measures have been adopted in the instrument to ensure the accurate measurement under the interference of external electric field.
