T&R pt30-10

T&R PT30-10 DC

The PT30-10 high voltage dc test set is designed to perform tests on installed cable and jointing systems. The unit has a variable output voltage with a maximum of ±30kVdc (PT30-10). Both units have 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 units include 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 2.5kJ on each output, corresponding to 10F at 18kV or 4F at 30kV. 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 both units, allowing higher load capacitances to be safely discharged.

The output voltage is metered by two large, linear, analogue instruments marked 0-20kV (PT18-10) or 0-30kV (PT30-10). Test object current is metered by two further analogue instruments with 0-10 scale marking. The meters read 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.

  • Delivery & Collection Information

    We use next day couriers to deliver all our test instruments.  That means it doesn’t matter if you’re 2 or 200 miles away, we can have the test equipment you need, delivered first thing, next day.

    When you have finished with the test equipment we can arrange for the same courier to collect it from you.

    We also offer a same day delivery service for when you really need the test equipment urgently.
