Power Quality

Sophisticated motors, drives and other electrical devices in today's workplace require a high level of power stability. When dealing with sensitive, high-tech equipment, even the slightest disruption in electrical service can result in costly production delays.

If your operations suffer from unpredictable power disturbances that result in downtime, lost data, equipment damage or other adverse outcomes, we can help.

Our Power Quality service will:

  • Identify electrical problems at your facility
  • Determine the causes
  • Recommend cost-effective solutions

When motors stall, circuit breakers trip, lights flicker or computers lock up, it could be signaling a power quality issue within your facility.

Many power-related operating problems originate from the customer's side of the meter. Most minor issues can be solved quickly and simply. Others more subtle in nature may require more in-depth analysis. Whatever the case, our community-owned utility is here to assist.

If you are experiencing an energy-related problem, give us a call. We'll meet with you to gather the facts and discuss your concerns. An energy engineer from our power supplier, Wisconsin Public Power Inc., will use the best technology available to identify the problem. We'll inspect your facility inside and out, monitor your equipment and conduct readings to help pinpoint the source.

We'll develop a plan to collect the data needed to improve the electrical performance of your operations. Using sophisticated monitoring equipment, our power quality specialist will analyze the data and discuss various approaches to solving your power quality issue.

In circumstances where you may be experiencing problems as a result of disturbances on our system, we'll keep you informed as we work to quickly remedy the situation.

When the problem is rooted within your facility, we will assist your staff or electrical contractor in devising a plan to correct the matter. Or, if you need help identifying someone to do the work, we can even provide a list of qualified experts in the area.

Even if you are not currently experiencing power quality problems but would simply like more information on power quality issues for planning purposes, consider giving us a call. We have useful information available at no cost to you, as well as other resources that you may wish to use or purchase.

Power Factor Correction Service

For large commercial and industrial customers (those billed on either the Cp-2 or Cp-3 electric rate), their facility's power factor is a component of the electric rate. The power factor is used to adjust a customer's monthly electric demand. For customers whose power factor is below .90, their billed monthly electric demand is increased; those with a power factor greater than .90 will have the billed monthly electric demand decreased.

Improving power factor will allow large commercial and industrial customers the opportunity to reduce power factor penalties, lower line losses, and increase electric system capability within their facility.

Two Rivers Water & Light's Energy Services Specialist, Frank Barth, is available to assist large commercial and industrial customers in analyzing how their facility's power factor is effecting their electric bill and what changes can be made to improve the power factor and reduce the electric bill.

Infrared Testing

We coordinate this low cost and efficient inspection service which locates electrical faults and mechanical problems due to overheating prior to failures and emergency repairs of your internal electric distribution system. Examples of items that can be scanned include electric connections, circuit breakers, motors and capacitor banks. The tests and inspections are in compliance with the current standards for Infrared Thermography Inspection/Testing including: ASNT, ASTM, ANSI, EPRI, IEEE, NEMA, NETA, and OSHA.

Infrared inspections can also be utilized to locate areas of heat loss. Examples of this type of use include detecting areas of air infiltration or lack of insulation in a building envelope. Also, this type of inspection can determine the heat loss for tanks of hot water, molten metal or plastic.

Upon completion of the infrared inspection service, the vendor will submit a written report to the customer containing the following information:

  • A complete list of all of the electric systems and equipment scanned.
  • An analysis of each condition that requires further investigation or correction.
  • An infrared image and a still camera photo of each problem detected. The images will be displayed side-by-side and each shall have an indication of the specific location of the problem.
  • The analysis of each problem will indicate the temperature of the "hot spot", the temperature rise of the "hot spot" over ambient temperature, an evaluation of the cause of the problem, and a recommendation for repair or correction.

The report provides the customer with information needed to correct the problem(s) before they cause serious destruction of equipment and/or expensive outages, or become safety issues for the public and/or employees.
