ON SITE CERTIFICATION OF THE PROTECTION

Advantages :

Final test on a definitive installation.

Benchmarking : same test whatever the detector trademark and the current sensor type.

Quality of the certification same as real tests.

Reduced use cost : low labour required.

Avoid destruction of equipments nearby the fault (telco, ).

Security of the persons (Test in LV).

Easy to carry in S/S.

IDC20K :

Power injector operating in low voltage.

Creation of arbitrary waveforms (reproduction of short circuits).

Portable equipment.

Modular till 20 000 A (2 500 A per module)

Production of a short circuit in low voltage :



Definition of the characteristics of injected short circuit :

1. Theoretical template

Scaled according to the distance and the short circuit resistor.

2. Template recorded by RL-PROTECT

Oscillodisturbography

3. Simple instruction

(Constant current)

4. Customized template

(Editable file)
