Product Overview
The dual‑mode PD sensor combines TEV transient earth voltage and AA ultrasonic sensing, specially designed for metal‑clad switchgear insulation monitoring.
‑ TEV detects high‑frequency pulses for hidden internal discharge and poor contact faults
‑ AA ultrasonic catches surface discharge on insulators and busbars
Two‑channel cross‑verification suppresses on‑site background noise for reliable insulation assessment. Magnetic attachment enables fast on‑site setup without equipment alteration.
