How to Identify: Use a multimeter to measure the load on each phase. If one phase is carrying significantly more current than the others, it indicates an imbalance. There are three main methods used to control the voltage at the end of a distribution feeder – By using control equipment to vary the voltage at the supply end of the feeder or at the load end and by controlling the current in the line by changing the power factor. Uni-Directional – They can only. Check the electrical load and ensure that the sensors do not exceed the 10 Amp maximum. Check each wire for damage that may lead to a short. Check the tightness of electrical connections along the power supply. Installation Select an appropriate location: It is usually installed inside the distribution box, close to the power inlet side, in a place that is convenient for installation and maintenance.
