These dips are caused by sudden increases in loads like short circuits, motors starting, electric heaters turning on, or loose connections. These occur in circuits with poor or damaged voltage regulators, but there can be other causes as well
Fixing Sags/Dips and Swells

A good power conditioner will filter and clean the incoming power. This will boost the longevity of anything connected to the power.
UPS systems are a reliable solution to power-related issues. These UPS systems produce constant power to critical equipment in the event of a stoppage or complete loss of utility power.
