Power Quality Problems

Studies show that up to 80 percent of most small business’ power quality problems are caused by disturbances created inside of a facility or business. (See the chart below.) When large power users in a building, such as fans and air conditioning equipment, cycle on and off, they can cause power “dips” and surges that affect other equipment in the building. Lightning is another major source of disturbance, accounting for more than 10 percent of power disturbances. That’s why it is important to have power quality protection at the incoming utility meter and at each piece of sensitive electronic equipment throughout your facility.
