Service Details

Moisture and trapped gases inside SF₆-filled equipment significantly reduce dielectric strength and can lead to partial discharge, corrosion, and insulation failure. Moisture removal and degassing are critical activities during commissioning, maintenance, leakage repair, and long shutdown periods.

EngineerBari™ performs controlled degassing and deep moisture removal using approved vacuum, filtration, and drying techniques in accordance with IEC standards and OEM guidelines.
