As an integral part of a traction system, electric motor plays a critical role in the national economy where its applications permeate all industries. The electric motor is also the fundamental element of everyday's lives where its normal operation is a necessary component for all industries. Therefore, it is of great significance to maintain good working order for the electric motors. The petrochemical industry uses a large number of low-voltage motors comprising of different models and specifications. Today, digital, microprocessor based motor protection relays have provided significant advantages for enterprises by reducing labor costs, improving efficiency and enhancing safety as well as reliability. As a result, motor protection relays have won industry-wide recognition as a necessary companion product of electric motors.
An example of a petrochemical project consists of one 10kV main substation, three 380V distribution substations and over 300 low-voltage motors requiring digital protection, monitoring and control devices.
