Please note this unit has been discontinued

The T&R PT18-10 mk2 High Voltage DC Cable Test System is a high voltage DC test set designed to perform tests on installed cable and joining systems. The T&R PT 18-10 has a variable output voltage with a maximum of ±18kV DC and a maximum charging capability of 10mA. The PT18-10 includes 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 10mF 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 that allows higher load capacitances to be safely discharged. The mk2 unit introduces 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. 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 T and R PT18-10 HVDC cable tester uses a high quality plug and socket system, allowing for easy cable replacement.

The mains supply switch is key operated which prevents unauthorised personnel operating the device. For added safety a zero-volt interlock feature is fitted that prevents the unit being energised unless the control is at zero. The T & R PT18-10 is housed in a robust case that in turn is protected by a padded jacket. It comes supplied with test leads, mains lead, manual discharge stick and an operating manual.
