The 15 kV Burn-Down Unit T 22/13 B is a very powerful,

portable, high voltage unit which is primarily used

for locating faults in power cables of the low and medium

voltage, mains, as well as in control cables.

The high output power and short circuit of the unit

make it possible in many cases to convert high impedance

and intermittent cable faults into low impedance

shunts up to dead short circuits without difficulty or to

dry wet cable sections.

The shockproof enclosure of all high voltage parts of the unit

and automatic discharging of the test object after shutdown/

power failure guarantee maximum protection for the

operator and the equipment

Use

The unit acts as a current source for locating faults in

power and control cables. It is primarily used for burning

down high impedance and intermittent cable faults in low

and medium voltage power supply networks.

In addition, it can be used in conjunction with the appropriate

connecting devices and a time domain reflectometer

(TDR) for prelocation with the Decay/Arc Reflection

Method.
