High Voltage Cables and Joints tester – Overview The Test PD is a compact, portable device for the effective testing of cable heads and cable joints under a voltage of 6 kV and higher. The device is easy to use and has an advanced system integrated into its software, which allows the user to quickly evaluate the condition of the analysed object. This makes the device user-friendly for service personnel as it doesn’t require special training. To test a cable joint, switch on Test PD, install it on an insulating stick and bring it close to the tested object. The information about the current joint condition will be immediately displayed in the form of 4-colour histograms and a cross-section of the high voltage cable. The Sonel TestPD mobile application for Android devices allows for remote reading of the instrument’s indications.
