- Burning of high resistive faults
- Low- potential free voltage avoids damage to other conductors
- Adjustable current limiter
- Overload protection
- Automatic discharge
The cable burn unit BT 500-IS-1 is a small portable unit for the burning of high resistive faults on low voltage cables as pilot, control and communication cables.
With the adjustable output voltages of 0.5, 1 and 2 kV and exceeding of the maximum permitted voltages for these types of cables is almost impossible.
TheBT 500-IS-1 is also a powerful sheath tester and has a pulsed output voltage for the pinpointing of sheath faults.
The voltage supply with an adjustable output voltage of 0 to 2 kV and an maximum test current of up to 1 A has a symmetrical output voltage, which means that a potential free connection to a cable pair is possible.
