WebSelecting the Right DC Earth Fault Locator: It is advised to choose a kit that provides higher output DC impedance (greater than 100 kΩ). This will avoid creating a faulty alert on the DC system, also safe for sensitive relays in the DC system. The possibility of maloperation of the DC system is reduced by choosing this method. WebGround fault interrupters are designed to protect from electrical shock by interrupting a household circuit when there is a difference in the currents in the "hot" and neutral wires. Such a difference indicates that an abnormal diversion of current from the "hot" wire is occuring. Such a current might be flowing in the ground wire, such as a ...
