Transient voltage defined as voltages 110% above service voltage.
Power Quality Management
Transient voltages split between the utility side and the consumer side.
- The utility side can comprise up to 20% of all transient voltages. The 20% is broken into two categories: lightning with 15% and miscellaneous with 5%. Miscellaneous is defined as tree limbs touching power lines, vehicle/pole accidents, animals such as squirrels, raccoons, or birds becoming part of the circuit, and/or a system grid switching.
- The consumer side can comprise 80% of transient voltage generation. A motor that cycles on and off automatically such as refrigerators, furnaces, air conditioners, washing machines, and dryers generate disruptions. Motors that you turn on and off such as garbage disposals or vacuum cleaners can generate these interruptions. The home-shop attached to the residential service panel that makes use of drills, saws, lathes, welders, and other shop equipment can create additional fluctuations on the residential electric circuits.
