What is KVAR?: KVAR is an Intelligent Motor Controller (IMC) and is capable of fine tuning the electrical motors. This fine tuning reduces heat generation, reduces Amperage and results in reduced consumption of electricity (KW-hr) through Optimizing the Power Factor (PF) of the individual load.; The way KVAR saves energy is by reclaiming storing and supplying power to inductive motors and loads. All induction loads consume two kinds of power, one is Reactive Power and the other is working power or KW.; More

Energy Costs: Energy costs continue to rise. Oil is at an all-time high, driving gas prices to $3 per gallon and more. The cost of electricity is also going up. According to the 2005 Department of Energy report, both demand for electricity and the cost of electricity continue to climb, with no relief in sight.; For many businesses, the cost of energy is one of the highest expenses. Yet business owners have few options for controlling or reducing energy expenses without compromising operations.; More

What is Surge Protection?: Surge protection does just that — it protects equipment form electrical surges. Simply put, the surge protector acts as a pressure-sensitive valve that opens when there is too much electrical pressure. To understand the value of surge protection, we need to understand electrical surges and their impact on equipment.; When you think of voltage, think of it as a measure of electrical pressure. When the increase in electricity lasts for three nanoseconds (a trillionth of a second) or more, it is called a surge. When the increase in electricity lasts for one or two nanoseconds, it is called a spike.; More

What are Voltage Transients?: Sudden, short-duration, high-amplitude disturbances in the normal voltage levels across power lines are called voltage transients. Although lightning causes some of these voltage transients, most are caused by the switching on and off of internal and external loads, and occur regularly on any power system.; The typical transient produces an oscillatory event that continues for a period of approximately 6.5 microseconds, becoming damped out after about three cycles. These voltage transients occur whenever inductive loads such as transformers and motors are switched on and off, and result from sudden dissipation of instantaneous stored magnetic energy in the rest of the system.; More
