DFA 300 – Partial Discharge Surveyor and it combines radio frequency interference (RFI) and acoustic emission (AE). Perfect tool to identify and locate insulation defects.
– Safe and effective method for PD detection
– Instrument uses both RFI and acoustic technology
– Registers RFI from apparatus with insulation problems including PD and arcing
– Locate and diagnose internal problems using the acoustic sensor on grounded surfaces
