Protection devices are an important part of the power supply system. They have evolved from simple microprocessors in 1985 to the advanced numerical relays of the current era. The numerical relays are a focal point of interest in the account that can be programmed. Protection devices using numeric protection relays are advantageous in the account as they provide better protection, reliability, troubleshooting and fault information.
Over the period of time, electrical engineering has evolved from static to dynamic studies. Now there are advances such as the digital signal processor and the computational hardware that improves the efficiency of the numerical relays in the protection of the devices. The current protection devices of the power system present the user with integrated functions. The numerical power system protection devices can perform multiple tasks on attributes such as protection, control, monitoring and measurement. In addition to this, the communication capability of these relays provides remote control and data transfer in real time.Now the conventional system of electromechanical and static relays is generally restricted to the single-function protection strategy. This shows the tactical dexterity of a digital relay system.
