Reading 3 phase voltage
WebOct 1, 2004 · Typically on a 120V circuit, you should get a reading of between 115V and 125V. Let's suppose you measure 118.5V. Neutral-to-ground voltage. This is a measurement of voltage drop (also called IR drop). It's caused by load current that flows through the impedance of the neutral wire. Let's suppose you measure 1.5V. Phase (hot)-to-ground … WebPhase-to-phase measurements simplified. L1, L2, and L3 (or Line 1, Line 2, and Line 3) are commonly used naming conventions for the wires in three-phase alternating current (AC) …

WebLine voltage refers to the amount of voltage measured between any two line conductors in a balanced three-phase system. With the above circuit, the line voltage is roughly 208 volts. Phase voltage refers to the voltage measured across any one component (source winding or load impedance) in a balanced three-phase source or load. WebThis is the 277-600 volt range, and most commonly you’re dealing with voltages at 277/480. Just like 120/208 means that between hot and neutral you have 120 volts, and between two hots you have 240 – in a 277/480 service the voltage between hot and neutral is 277 and the voltage between two phase (hot) conductors is 480 volts.
WebThree-phase/3-phase: A wiring system consisting of four wires and used in industrial and commercial applications. This system is suitable for installations requiring large motors. It consists of three hot wires and one ground wire. The voltage in each hot wire is out of phase with the others by one-third of a cycle, as if produced by three ...
