T&R PT15-10S DC Cable Test System

The T&R PT15-10S 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 +15kVdc 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 unit 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 1.25kJ, corresponding to 7.5µF at 15kV. A DP20 discharge probe is also supplied as standard with the PT15-10S, allowing cables with a capacitance of up to 12µF to be discharged at 15kV. The output voltage is metered by a large, linear, analogue instrument marked 0-15 kV. The current in the test object is metered by a second analogue instrument with 0-10 scale marking. The meter reads 0-10 mA directly, or 0-1 mA when the ?10 push button is operated.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.FEATURES0 to - 15kVdc output voltage. 10mA output capability. Both voltage and current metered on HV output. Automatic earth system for dumping capacitive loads. HV output plug & socket. Key operated supply switch to prevent unauthorised operation. Zero-volt interlock. Visual indication of test piece failure. Compact unit with lightweight insulated case.T&R PT15-10S SpecificationsOutputUnit TypeVoltageContinuous5 MinutesPT15-10S0 to - 15 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.MeteringThe positive and negative output voltages on the PT series are metered on the HV output by separate analogue instruments.Unit RangeAccuracyPT15-10S0 to 15 kV.+1.5% of full scale.The output current on both of the outputs is metered by a dual range analogue instrument.
