Power line transients
Heavy electrical loads from nearby machinery or equipment (for example,
elevators or electric welders) can cause intermittent system problems with
sophisticated electronic equipment, even if that equipment is on a separate
circuit breaker. When faced with these conditions, provide a separate,
completely independent power panel with an isolated ground and circuit
breaker coming directly from the main building power source or secondary
power source.
If necessary, an HP representative can measure your power line noise level
and make appropriate recommendations concerning the use of line
treatment devices.
