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.
