Description

The PT30-10 Mk3 Test Set conducts tests on installed cable and jointing systems. It offers a variable output voltage of up to ±30kVdc and a maximum charging capability of 10mA. It features a zero-volt interlock that prevents switching on the output unless the output control is at zero. Additionally, an automatic load discharge system safely discharges the cable under test when switching off the output or in case of a breakdown.

The internal dumping system has a maximum discharge capacity of 2.5kJ on each output, corresponding to 4µF at 30kV. In the event of a test object failure, the overload circuit automatically shuts off the output voltage and grounds the output using the internal discharge circuit.

The PT30-10 Mk3 comes standard with a manual DP40 discharge probe, enabling safe discharge of higher load capacitances. It also introduces automatic 115/230V mains voltage selection for seamless transition between site voltages.

Two large, linear, analogue instruments marked 0-30kV measure the output voltage. Two additional analogue instruments with a 0-10 scale accurately measure the current for the test object. The HV output utilizes a high-quality plug and socket system for effortless cable replacement.
