INTRODUCTION FOR ELECTRICAL MOTOR CONTROL DRIVE AND SENSOR MAINTENNACE FOR ELECTRICAL AND NON ELECTRICAL PERSONNEL
Single Phase power is a two wire Alternating Current (AC) power circuit powers the household items like lights, TV which is used to power 120 volt plug loads and smaller HVAC systems. In single phase circuit, there will be only one phase, i.e the current will flow through only one wire and there will be one return path called neutral line to complete the circuit.
Three Phase power is a three wire Alternating Current (AC) power circuit. Three phase is a medium or high voltage system with Three live conductors and one neutral. For three phase, power can be drawn either by the delta configuration or the wye configuration.
In industries, more than 60 or 70% load is of motors which are designed for three phase for higher efficiency.
Sensor is a device, used to measure a object, such as pressure, position, temperature, or acceleration, and respond with feedback.
