T&R PT18-10 mk3 DC Cable Test Systems

The T&R PT18-10 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 +18kVdc 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. 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 T&R PT18-10 mk3 unit, allowing higher load capacitances to be safely discharged. FEATURES +18kVdc output voltage. 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. Visual indication of test piece failure. Automatic mains voltage selection. T&R PT18-10 Mk2 Specifications Output Unit Type Voltage Continuous 5 Minutes PT18-10 0 to +18 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. Metering The positive and negative output voltages on the PT series are metered on the HV output by separate analogue instruments. Unit Range Accuracy PT18-10 0 to 20 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 PT18-10 10 mA. 1 mA. +2.5% of full scale. 1 mA +2.5% of full scale. Overload Protection The PT18-10 is protected by an overload trip on the output that operates at 12mA. Supply Requirements 115V/230 V+10% auto-selecting 50/60 Hz 1ph 600 VA 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. General Storage temperature -20° C to 60° C. Operating temperature 0°C to 45° C. Dimensions 471 x 144 x 362 mm. Weight 17 kg unit only. 25 kg including bag & leads. T&R PT18-10 mk2 warranty 1 year.
