We manufacture Tan delta tester (Tanδ, TD), also called dissipation factor or loss angle, is used for measuring the degree of deterioration of transformer,generator and so on.

(1) Automatic transformer tan delta tester is a high accuracy instrument, which can be applied to automatically measure electrical loss tangent and capacitance of all kinds of high voltage electrical equipment.

(2) The variable frequency power supply uses a high-power switching power supply. Output 45Hz and 55Hz pure sine waves, automatically pressurize, can provide a voltage of up to 10kV; automatically filter out 50Hz interference, suitable for field testing with large electromagnetic interference.

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. transformer tan delta tester measuring circuit includes a standard circuit (Cn) and a test loop (Cx), as shown in Figure 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.
