- It´s
helpful to keep a running log
of when events occur.
Note date and time and be sure to record "specific" problems
and symptoms. For example, instead of "power surge at 8
a.m. March 8, 2001," write "lights flickered when air conditioning
came on at 8 a.m. March 8, 2001."
- If
the problem is with a specific piece of equipment or software,
refer to the instruction manual and contact the manufacturer
to determine if they can help identify the problem.
- Have
a qualified electrician check the wiring and grounding:
- Verify
proper wire sizing for your specific loads (for three-phase
systems in older buildings, neutral wires may be smaller
and not adequate for today's electronic loads),
- Check
all connections for tightness and clearances,
- Check
that your service is properly grounded to National Electric
Code, Article 250,
- Verify
there is only one neutral-to-ground bond at the main service
entrance and none in downstream panels or receptacles,
- Check
proper outlet wiring, and verify that your loads are properly
balanced and no circuits are overloaded.
- Determine
if the disturbance is caused by other equipment on the
same circuit and isolate sensitive equipment or move it to
a dedicated circuit. Contact a qualified electrician for assistance
with installation of dedicated circuits.
- If you think
that Electrical Noise or Interference is causing a problem,
when the static occurs, disconnect the electric-powered
items in your home or building one at a time, or turn off
circuit breakers one at a time. When the static stops, you've
found the culprit. You can also try moving the equipment
that's effected to an alternate location in your building
to help determine the problem.
- Check
facility operation. Switching on and off of high current
electric loads or loads that are on very lengthy building
circuits can be a cause of voltage sags.
