HOW DOES THE CIRCUIT MASTER SAVE ELECTRIC DOLLARS? Kva (-) Kw (-) Kvar = Kwh There's a simple explanation, but first we must understand how electricity is delivered. All utility companies deliver Kva. We have all seen the transformers on the ground or the pots around the pole in the air. Each of these transformers has a number stamped on it for the potential electricity available for use from that location, i.e. 100Kva, 200Kva, etc. Depending on the need, these transformers could be for just one building or an entire street of homes. When the Kva comes through the utility meter, it is converted to active power known as Kw, and re-active power known as Kvar. Naturally the amount of Kw and Kvar is different and variable for each location. The Kw and Kvar are billed by the utility company in the form of Kwh. Therefore, Kw + Kvar = Kwh which reduces the amount of Kva available from the transformer. By reducing the Kw and/or Kvar, the Kwh billing will be reduced. As we all know, the Circuit Master can only reduce the Kw by improving the efficiency of consuming the Kw. This is done by improvement of the Power Factor. Since Kw is active power that the load needs to perform the work required, the only way to reduce it is by reducing the load or the load is turned off. If the load is reduced, the Power Factor will also be reduced because the load is now doing less work than it was intended to do thereby reducing its efficient use of power. The Circuit Master will keep the Power Factor high even with a reduced load, thereby improving the efficient use of Kw. Always remember improving a PF from .75 to .85 is a much greater improvement than .85 to .95 even though they are the same 10 point improvement. Kvar, on the other hand, is electricity line losses derived from the delivery of the electricity and resistance to the flow of electric current. Kvar is also needed to support magnetic fields created by motors. The Circuit Master replaces the majority of the Kvar losses from its internal capacitor bank that stores reactive power. This reduces the Kvar charges associated with the kwh billing. Although the charges are different for different utility companies, a general rule is Kvar accounts for 15% to 20% of the Kwh billing. If the rate is .10 per Kwh, approximately .02 of that comes from Kvar. By reducing 80% of the Kvar, the overall Kwh billing becomes .084 or approximately 16% savings on the bill. |
