Thiết bị kiểm tra phóng điện cục bộ NBD Technologies XDP-II
Partial discharge testing is a predictive & qualitative analysis tool that can warn of a potential upcoming system failure. The XDP-II is a powerful and flexible Partial Discharge Measurement System. It displays the Partial Discharge wave form and the built-in speaker plays a sound reproduction of the signal measured. Those can be recorded in the XDP-II along with date and time of the reading. The recorded measurements remain stored in memory allowing the transfer to a computer upon return from the worksite.
Applications:
- Quality control of MV/HV equipment on production line (transformers, switchgears, arrestors, insulators, couplers, etc...)
- Quality control of the insulators during installation or underground network repair (cable joints, elbows, etc.)
- Online follow-up of the ageing process of the critical components’ insulation (transformers, switchgears, cable joints etc.)
- Safety control prior to work conducted under charge.
- TEV testing on switchgear cabinets.
- PD detection in switchgear using the VIS capacitive coupler.
- Corona and Arc detection on aerial devices using the acoustic sensor.
- PD detection in oil-filled transformer using UHF antenna / HFCT clamp.
