The range includes primary and secondary current injection equipment up 6000A, voltage sources, micro-ohmmeters and high voltage test systems up to 100kV.
The PT18-10 and PT30-10 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) or 30kVdc (PT30-10). Both units 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.
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 or 4F at 30kV. 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) or 0-30kV (PT30-10). 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.
