WebMar 6, 2024 · V pq = (√3V LN cos30°) × 2 = 3V LN (equation 9) Thus, the voltage available to the relay for a phase-to-ground fault on the ungrounded system is three times the line-to-neutral normal voltage. Usually, the VT ratio of primary V LN: 69.3 V is used so that the maximum solid ground relay voltage would be 3 × 69.3 = 208 V.
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 ... highlight lines in excel 2007WebThe ground detector circuit makes a connection between the rotor ground and the excitation circuit, usually on the negative terminal as shown here.
