"GESPER Systems units work to provide electric current optimization. Electricity as it moves from the power company to the customer's meter loses' the properties of the original power supply. The electric companies utilize much of the same technology as found in the GESPER Systems to try to correct the energy between the power station and its customers. However, by the time the electric power is received at your meter, the circuit is typically not “optimal”. The use of this power can cause motors to overheat, lights to fail due to unstable voltage, and equipment to be damaged. This is why most computers and electronics are protected by a surge protectors. Very high end audio electronics typically also have very expensive power conditioning units to stabilize the electricity and prevent surges."
