Features:

Good authenticity

The transformer is designed according to the real transformer to simulate all the structure and electrical characteristics of the transformer.

Fault simulation

The device can simulate the each faults of transformer such as partial discharge, internal winding fault, damp of the bushing, temperature rise etc.

Controllable discharge

A single or composite PD signal can be simulated and control the starting voltage, the extinction voltage and the discharge intensity of each discharge signal.

 Detection diversity

It can provide a test platform for Transformer PD detection, oil analysis, infrared temperature measurement, frequency response, vibration analysis and other test techniques.

Measurement transfer

Built in pulse current correlation coupling and calibration unit, can synchronously detect the PD level of the experimental device, and be used as the basis for the instrument evaluation.

Good stability

Each fault model can be reused and the fault characteristics are stable.

Built-in sensor

Built in ultra high frequency, ultrasonic, temperature sensor, and it is convenient for measurement and comparison

Visualization

The fuel tank is provided with a plurality of fluoroscopy windows, and a built-in infrared video probe is used to observe the internal state and capture the discharge video. 

Easy operation

The occurrence and disappearance of each fault can be directly controlled outside the device.

Safe and reliable

Adopt the fully enclosed type oil tank structure, and each component is reliably grounded.
