The PD Hub is the core of the PD monitoring system and is available as a 3, 6, 9 and 12-channel device. Its UWB acquisition unit operates from 16kHz to 30MHz with a fast sampling rate of 100MS/s and captures the entire waveform of a large number of pulses. The TF Map allows to differentiate between different pulses with different shapes (TF Map) hence improving the signal to noise ratio and collect mainly pulses related to PD activity. The unit is powered and protected by a LV switchboard. The PD Hub is available in IP65 as well as IP68, where required. Usually the PD Hub is installed close to the cable terminations and cable joints
