The PT15-10S Mk2 Test Set provides a variable output of zero to 15kV DC with a maximum charging capability of 10mA. It includes a zero-volt interlock that prevents the output from being switched on unless the output control is at zero. An automatic load discharge system is integrated, discharging the cable under test when the output is switched off or a breakdown occurs.

The internal dumping system has a maximum discharge capacity of 1.25kJ, which corresponds to 7.5μF at 15kV. The PT15-10S Mk2 DC Test Set comes with a standard DP20 discharge probe. This allows for discharging cables with a capacitance of up to 12μΩ at 15kV.
