Details

The T&R PT18-10 high voltage dc test sets are designed to perform tests on installed cable and jointing systems. The units have a variable output voltage with a maximum or ±18kVdc (PT18-10).

The PT18-10 have a maximum charging capability of 10mA. A zero-volt interlock is fitted that prevents the output being switched on unless the output control is at zero.

T&R PT18-10 mk2 features:

  • ±18kVdc output voltage
  • 10mA output capability
  • Both voltage and current metered on HV outputs
  • Automatic earth system for dumping capacitive loads
  • HV output plug & socket system
  • Key operated supply switch to prevent unauthorised operation
  • Zero-volt interlock
  • Visual indication of test piece failure
  • Automatic mains voltage selection

The units include an automatic load discharge system that discharges the cable under test when the output is switched off or a breakdown occurs. The internal dumping system can discharge a maximum of 2.5kJ on each output, corresponding to 10□F at 18kV.

In the event of a test object failure, the overload circuit will automatically switch off the output voltage and earth the output via the internal discharge circuit. A manual discharge probe is also supplied as standard with both units, allowing higher load capacitances to be safely discharged. The mk2 units introduce automatic 115/230V mains voltage selection, allowing easy transition between site voltages.

The output voltage is metered by two large, linear, analogue instruments marked 0-20kV (PT18-10). Test object current is metered by two further analogue instruments with 0-10 scale marking. The meters read 0-10mA directly, or 0-1mA when the ÷10 push button is operated.

The HV output from the unit uses a high quality plug and socket system, allowing for easy cable replacement.
