T&R PT15-10s High Voltage DC Cable Test System

The T&R PT15-10s High Voltage DC Cable Tester is designed for performing commissioning tests on installed cables and cable joints. It is also capable of routine HV DC testing of electrical plant and components. The PT15-10s is continuously variable from 0-15kV DC 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 7.5mF at 15kV. A DP20 discharge probe is also supplied as standard with the PT15-10S, allowing cables with a capacitance of up to 12mF 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. The T and R PT15-10s is housed in a grounded chassis which in turn is housed in a insulated moulded case. This case is fitted with a lid which incorporates a moulded handle. The PT15-10s is also provided with a shoulder carry strap.
