"DC Cable Test Set with +/- 30kV, 10mA output"

  • Description

    T&R PT30-10 mk2 DC Cable Test System

    • ±30kVdc output voltage (PT30-10)
    • 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 - for safety
    • Visual indication of test piece failure
    • Automatic mains voltage selection

    The T and R PT30-10 High Voltage dc Test Sets are designed to perform tests on installed cable and jointing systems. The T and R PT30-10 Mk2 has a variable output voltage with a maximum of ± 30kV dc (PT30-10). This DC test system has a maximum charging capability of 10mA. For safety a zero-volt interlock is fitted that prevents the output being switched on unless the output control is at zero.

    This DC test system 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 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 the unit, allowing higher load capacitance's to be safely discharged.

    This latest Mk 2 version of the T and R PT30-10 Test Set has an automatic 115V/230V mains voltage selection, allowing easy transition between site voltages without the risk of damage.

    The output voltage is metered by two large, linear, analogue instruments marked 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.

  • Specification


    The T & R PT30-10s cable test systems have high quality high voltage output connectors, and are supplied with detachable, partially screened output cables.

    Test Set Voltage Continuous 5 minutes
    PT30-10 0 to ±30kV 5mA 10mA

    The above intermittent on times must be followed by an off time of 15 minutes, and is based on an 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.

    Test Set Voltage Range Accuracy
    PT30-10 0-30kV ±1.5% of full scale

    The output current on both of the outputs is metered by a dual range analogue instrument. The 1mA range is selected by the¸10 pushbutton adjacent to the mA meter.

    Test Set Current Range Accuracy
    PT30-10 10mA ±2.5% of full scale
    PT30-10 1mA ±2.5% of full scale

    Overload Protection

    • Protected by an overload trip on the output that operates at 12mA.

    Load Discharge System

    The PT30-10 is fitted with an automatic internal load discharge system that grounds the load via a 20kW resistor on each output when the output is switched off. The discharge system is rated to dissipate 2.5kJ once every 15 minutes on each output. The PT30-10 can discharge a maximum load capacitance of 4mF per output from 30kV.

    • Maximum discharge energy 2.5kJ 2.5kJ
    • Maximum discharge capacitance 10mF 4mF from unit max output voltage

    Supplied with a DP40 manual discharge probe to allow the discharge of higher capacitance loads. The DP40 discharge probes consist of a pointed probe connected to a 5m long earth lead via a series of surge resistors with an insulated handle. The earth lead insulation is clear silicone allowing the conductor to be easily inspected, and is terminated in an M6 hooked crimp.

    • Discharge probe max discharge voltage - 40kV
    • Resistance - 60kW
    • Maximum discharge energy - 7.2kJ
    • Maximum discharge capacitance - 11mF from DP max rated voltage

    Supply Requirements

    • T&R PT30-10 mk2 115V/230V±10% auto-selecting 50/60Hz 1ph 750VA max

    Protection and Safety

    • The output of the unit is protected by an overload trip, and the input and control supplies are protected by fuses.
    • The T&R PT30-10 is designed to meet the requirements of BS EN61010.
    • An earth terminal is provided on the units which must be connected to a low impedance local earth.
