Power Correction Systems:

Using a patented instrument (sizing unit) in conjunction with standard electronic testing equipment Power Correction Systems, Inc. (PCS) has developed an innovative method for on site analysis of motors and motor control centers.

This allows us, under actual working conditions, to simulate different solutions, to find the power factor and capacitive value for an optimal correction, without any risk of over compensation and to evaluate the impact of capacitors on harmonics.

Since motors and motor control centers are measured under existing and corrected conditions we can calculate the savings generated by the installation of capacitors.

In addition to the above benefits, the cost of individual compensation is 20% to 40% lower than any other method of compensation.

In the event that power factor surcharges have been eliminated at the main panel, we can still offer significant savings through the reduction of line losses, improved voltage level and distribution capacity as well as longer life expectancy of motors and transformers.

PCS - Four steps to energy efficiency and cost savings:

Step 1 – Feasibility study:

To identify overall savings potential, we must compile the following:

  • Copies of the most recent 12 months utility invoices or billing history.
  • A list of your electrical motors with their H. P. and hours of operation.
  • The plant layout with dimensions, motors and meter location.

This information is then evaluated through our proprietary computer analysis program to provide at no cost a feasibility estimate of potential savings and cost.

Step 2 – On-site analysis.

If the feasibility study in step 1 indicates project viability; a PCS technician along with your local sales agent will propose an on-site analysis at a cost refundable if a purchase order is received.

Using our patented sizing unit in conjunction with standard testing equipment, we measure and report each of the following, under existing and corrected conditions:

Power factorAmperageVoltageLength of conductorResistance of conductor

HarmonicsHours of operation

Step 3 – Software analysis.

All results tabulated during the on-site analysis are then input to our proprietary computer analysis program to produce the following report: (The following example represents a partial list of motors measured in this project)

Product and installation:

ABB Control Inc., the largest manufacturer of capacitors in the world, manufactures all capacitor boxes provided by PCS.

Capacitor boxes are installed by customer’s electrician or by independent electrical contractors under the supervision of PCS.

Conclusion:

If your facility uses electric motors, a power factor below unity is present and savings can be realized by improving their power factor.

If you are currently paying, to your utility provider, a power factor surcharge, you can received the maximum benefits through the elimination of that surcharge and the reduction of line losses.

If you have already eliminated power factor surcharges at your main panel, PCS may still offer significant savings through reduction of line losses.
