The TE PDS provides an inductive and a capacitive sensor for quality assessment on various electrical installations. The most common application for this instrument is to check the quality in terms of PD of joints and terminations immediately after installation. The TE PDS is used exclusively on insulated HV installations.
Detecting possible weakspots is done with the capacitive sensor, which picks up electric field changes due to PD. The intensity of the signal in pico coulomb decreases with increasing distance to the PD source and is immediately transformed into a dB-value and displayed. This change of signal level leads to the exact location of the PD.
The TE PDS is also applicable on shielded joints if the shield is grounded on both sides of the joint. This measurement uses the built-in inductive sensor. The course of the signal level along the joint indicates the exact location where highest level is indicated closest to the PD fault location.
PD pulses at the respective faults are reliabley detected and evaluated by the integrated VHF senors in the frequency range of 100 MHz. A high indication will provide higher reliability and quantification of the weakspot. The signal levels are indicated visually and acoustically.
