Voltage Sag
Voltage Sag : Voltage Sags are momentary (typically a few milliseconds to a few seconds duration) under-voltage conditions and can be caused by a large load starting up (such as a air conditioning compressor or large motor load) or operation of utility protection equipment. Sags often appear as flickering lights and can cause equipment shutdown. A sag of just a few milliseconds can mean a complete blackout to some sensitive equipment
