DL/T 555 Guide for withstand voltage and insulated test of gas-insulated metal-enclosure switchgear on-site.

Features:

Good authenticity

The switchboard is designed according to the real GIS switchgear to simulate all the structure and electrical characteristics of the GIS.

Good integrity

Step-up transformer and coupling capacitor are built in GIS enclosure.

Fault simulation

The model can simulate all kinds of discharge type for GIS switchgear such as Point discharge, Suspension discharge, Air- gap discharge, Particle discharge, Surface discharge etc. A variety of discharged can be compounded production.

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 pulse current, ultra high frequency, ultrasonic, High frequency, SF6 gas analysis and other technical tests.

Measurement transfer

Built in pulse current correlation coupling and calibration unit, can synchronously detect the PD level of the experimental device.

Good stability

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

Easy operation

The occurrence and disappearance of all kinds of faults can be directly controlled outside the device.

GIS spacer diversity

The GIS spacer have different type such as full shielded type, without shielding type, casting port type etc.

Visualization

Built-in infrared video probe, it is easy to observe the internal state, capture the discharge video.

Built-in UHF sensors

Built in UHF Sensors and it is convenient for comparison with the tested instruments.
