The HV Diagnostics TD30 is a battery powered system that is directly connected to the HVA30 series of VLF test systems. The standard “C” size alkaline battery cells last for some 10hours thus providing the capacity for many tests. The TD30 is supplied with 10 metres of output cable which is already terminated to suit the HVA30 test system. Companion operating software gives a complete picture of the tan delta measurement together with a real time display of the output voltage and current. The data transmission is via Bluetooth thus eliminating a direct connection between the TD30 and the data collection device.
