When power comes into a building, it is in AC, or "alternating current." AC current switches back and forth from positive to negative 60 times a second. It is carried into the building on the live wire. A second wire, called the return wire, carries the current back out of the house...
Figure 2. A single-phase, two-wire system uses a current transformer and voltage transformer. With a single-phase, three-wire system (Figure 3), the total power is the algebraic sum of the two wattmeter readings. Each wattmeter is connected from one of the hot wires to the neutral, and...
§2. How to wire Three Phase AC Voltage Regulator? 2.1 Simple Type MGR-SCR3_LA Series This kind of simple type three phase AC voltage regulator uses a simple package (or easy assembling), with basic voltage regulation function, and it is cheaper than the normal type. A1, B1, C1 ports...
3Thread a 30-amp, 240-volt, 3-wire, UL-listed power cord through the strain relief. 4Transfer the appliance's ground wire from behind the green ground screw to the center screw of the terminal block. 5Attach the two hot leads (black and red) of the power cord to th...
With a three-phase 3-wire system (Figure 5), the two wattmeters measure phase current in any two of three wires. Each wattmeter measures a line-to-line voltage between two of the three power supply lines. In this configuration, the total power, watts, is accurately measured by the algebr...
(the downline loads on the other phase are trying to return current there). So that certainly could have caused what you describe. The cure is to search the panel for "shared neutral" situations (if wired in cable, the sure sign is a red wire on a 120V breaker) and make sure...
If you've studied our article on transformers, you'll know that they're electromagnetic devices that change low-voltage AC to high-voltage AC, or vice-versa, using two coils of wire (called the primary and secondary) wound around a common iron core. In a mechanical inverter, either an ...
