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 and 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 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. 

Key benefits:

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