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.

T&R PT30-10 Mk2 Specifications
Unit Type Voltage Continuous 5 Minutes
PT30-10 0 to ±30 kV. 5 mA. 10 mA.
The above intermittent on times must be followed by an off time of 15 minutes and is based on ambient temperature of 25° C.
The positive and negative output voltages on the PT series are metered on the HV output by separate analogue instruments.
Unit Range Accuracy
PT30-10 0 to 30 kV. ±1.5% of full scale.
The output current on both of the outputs is metered by a dual range analogue instrument. The 1 mA range is selected by the 10 pushbutton adjacent to the mA meter.
Unit Range Accuracy
PT30-10 10 mA.
1 mA.
±2.5% of full scale.
1 mA ±2.5% of full scale.
