Product Description

Product Description

PT line protection relays with 87T Differential protection transformer function

Easy-to-use protective relays for Medium Voltage applications with fast
delivery, ideal for Panel builders, Contractors, Partners and end users.
From overcurrent to advanced protection, with Arc flash protection, LPCTs,
LPVTs and Ethernet communication
AM2 protection relays integrate protection, control,
measurement, and automation functions in one device.

 

Functions and parameters

Main functions of AM2 Protection Relay for medium voltage under 35KV

AM2 Series Protection Relay is equipped with full protection functions. It is designed for fast installation, wiring
and operation.

Measuring three-phase current and zero-sequence current (Ia, Ib, Ic, I0), three-phase or line
voltage (Uab, Ubc, Uca), active power P, reactive power Q, power factor cosφ, frequency f.
 
Up to 8 -channel DI,Users can customize the name.
 
The relay supports tele-control and can be time synchronized.

The relay is equipped with strong fault recorder. All kinds of waveform and binary signals are to
be recorded.

A RS485 communication interface to support the IEC60870-5-103, Modbus and other protocol.

The full graphical programming technology, as well as stable and reliable protection relay library,
improve reliability and correctness of the procedure.

A dedicated chip is used in the relay to memorize the basic data after the loss of power supply. The
device can work properly after the resume of power supply.

Machine static low power consumption (about 4W), LCD module using the new technology, life
expectancy increased substantially.
