Burn down instruments

BT 500 IS-1

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 an exceeding of the maximum permitted voltages for these types of cables is almost impossible.

Simultaneously the BT 500-IS-1 is 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 a 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.

Key benefits:

  • Overload protection
  • Automatic discharge
  • Burning of high resistive faults
  • Low-potential free voltage avoids damage to other conductors
  • Adjustable current limiter
