Abstract
... In this paper, a DC/AC converter called inverter is proposed. This converter includes 12V converting 110V and 12V converting 220V circuits. In 12V/110V circuit, the IC555 generates a 240Hz signal that passes the IC4027 to obtain the 60Hz signal. By transistor C4016 and 12V/2V transformer, the signal ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
