The T&R PT30-10 high voltage dc test set is designed to perform tests on installed cable and jointing systems. The units have a variable output voltage with a maximum of ±30kVdc, with 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 T&R PT30-10 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 4µF 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 the PT30-10 unit, 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 0-30kV. Test object current is metered by two further analogue instruments with 0-10 scale marking. The meter reads 0-10mA directly, or 0-1mA when the ÷10 push button is operated.
Includes: Supply lead, discharge probe, spare fuse, PT30-10 operating manual, 5m HV output leads, 5m output earth lead.
