The family of microprocessors EZAS-2 type consists of modern devices for electrical protection automation (EAZ), which are used in monitoring the following medium voltage fields (SN), such as:

• power line field,
• linear drainage field,
• rail connector box,
• SZR automation field,
• asynchronous motor field,
• capacitor bank field,
• transformer field,
• measurement field.

The EZAS-2 relay panel supervises the following task groups:

• implementation of an appropriate set of protection for signaling and control of a chosen switchgear field (disrupted conditions),
• implementation of automation related to a given switchgear field,
• measurement and visualization of the selected values of electrical quantities,
• registration and visualization of events,
• communication with the user.

The advantages of EZAS-2 are as follows:

• the usage of microprocessors with arithmetic coprocessor and analog-to-digital converter,
• the usage of modern digital technology providing high parameters and characteristic stability, accurate measurements and reliable operations,
• two-channel current measurement, i.e. separately for small overloads and for short circuits (this increases primarily the channel resolution and accuracy of measurements),
• advanced dynamic properties,
• easy to install construction – especially in the compartment of auxiliary equipment.

Currently, the EZAS security and control unit is available in two versions:

1. EZAS 2C
2. EZAS 2P
