Literally it is the metering or conditioning of electrical current running through wiring that feeds electrical appliances, machinery or other electrical devices.
Electrical power that is delivered to your meter, either residential or commercial, varies or fluctuates. Notice has been made of lights that dim or grow brighter, screens that flicker or refrigerators that seem to speed up and slow down. This is a direct result of power fluctuation.
Fluctuation of current to electrical devices can cause additional wear and tear to your appliances, machinery and electronic equipment. This will cause your device to need repair or replacement sooner than with conditioned electricity.
All electrical devices obtain wear and tear when they start up. The best scenario for a motor is for it to rev up to speed and then remain at a constant speed. When you hear your refrigerator compressor rev up and down, what is happening is the motor had to work harder to get to operational speed. If it is continuously reving up and down, it is continuously adding wear and tear to your motor.
No. Varying current will cause wear on all electrical devices. Lights use either a filament or gas to provide illumination. The more a filament is heated and cooled, the more brittle it becomes and the sooner that it breaks. Gas inside of a bulb is the same way. The more that it is heated and cooled, the more of the gas that it burns and the sooner it needs to be replaced. Screens for Computers and Televisions work the same way.
The Green Box acts as a line conditioner. Electricity that is contained in The Green Box capacitors is introduced back into the power bars as it is called for. This is done via resistance placed on the capacitor that regulates when and how the electricity is fed back into the system. This creates a steady current that smooth out the peaks and valleys of non-conditioned current. If your lights dim every time the air conditioner comes on, The Green Box will eliminate that. Compressors and motors will run more consistently, use less energy and last longer.
It is estimated life of electrical devices can be 10% to 20% longer.
