Product Data

T&R Test Equipment is a market leader in the field of protection test equipment. The range includes primary and secondary current injection equipment up 6000A, voltage sources, micro-ohmmeters and high voltage test systems up to 100kV. The PT15-10S high voltage dc test set is designed to perform tests on installed cable and jointing systems. The unit has a zero to-15kVdc variable output 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 12μΩ to be discharged at 15kV.

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.

The output voltage is metered by a large, linear, analogue instrument marked 0-15kV. The current in the test object is metered by a second analogue instrument with 0-10 scale marking. The meter reads 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.
