Ans ScottyUK True, once the capacitor is charged, the motor and capacitor "bounce" the reactive power necessary to mainatain the electromagnitic field. Normally, only a portion of the reactive power is needed to establish and maintain the electromagnetic field, the remainder goes to...

Be careful. Powerboss is a wave chopper that chops current and voltage to your motor. This could damage the motor if the unit's circuits start to fail. They do nothing for I2R and power factor. Capacitors at the load will maintain the current and voltage, reduce I2R and bring the power factor...

Marke. What do you mean if the savings in kw is too significent the wire is too large. What is the definition of supply. The work component remains the same in the pf curve when the cap is introduced. The reduction is in the magnizing current, the current is reduced from the capacitor thru...

In answer to Marke. The extra current may be inductive, but it does contribute to kw usage in the I2R losses area. These losses are found from the motor to the meter in the way of heat. Put a capacitor at the load and the power factor will be increased and the kw will be reduced due to I2R...

Jbartos What type of process has this type of dynamics that would cause dangerous oscillations. What type of damage are you talking about. chronic or acute. I've put these on plastic extrusion, elevators etc without any apparent damage. Do you have a sourse reference?

The wasted watts are all the way from the motor to the supply source. The effect of the cap is from the point of installation. The utility sponsored ones are usually connected on their side of the meter or just inside of the meter. In each case the cusomer does not realize the benefits of...

True, the capacitor will supply the vars, just the point. When the "system" supplies the vars not all of the current is used for the maintenance of the magnetic field, the remainder goes to wasted watts, heat to the motor. By installining the cap, the wasted watts is no longer...

Installing a properly sized capacitor will make the motor run cooler and therefore longer. Also the power factor will be optimized to close to unity. And kw will be saved.

How are capacitors sized for surge protection? Are capacitors rated for surge protedtion?

Compensators at the load offer the best overall energy savings, for the customer and the utility. The benefits of compensation is realized from the point of installation on the line back to the power source. By placing the compensator at the load contactor or disconnect, all of the wire and...
