Brand T&R Test Equipment

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.

T&R PT15-10S Specifications

Output
Unit Type	Voltage	Continuous	5 Minutes
PT15-10S	0 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.
Metering
The positive and negative output voltages on the PT series are metered on the HV output by separate analogue instruments.
Unit	Range	Accuracy
PT15-10S	0 to 15 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
PT15-10S	10 mA. 1 mA.	±2.5% of full scale. ±2.5% of full scale.
