1.Product Introduction
1.1.Introduction RTU
ERT-200S is embedded in Distribution Automation SF6 gas insulated load break switch (Pole
mount) control box. It receives measurement information (3 phases current & voltages) and
status information from Switch, and meters current and voltage, detects FI, Line cut, Live
line/Dead line, Unbalance,Sectionalizeroptimizedfor remote control and automation systems.
ERT-200Smonitors not only electric qualityof distribution line but also, provides Section
operation in case of fault occurring and minimize its fault area.
All events occurring in the distribution line, are saved and provides fault analysis. With using
DNP3.0 Protocol, provides monitored status to SCADA for switch operation. Not only DNP3.0
Protocol, other communication protocols can be provided by user’s request.
As well as, controlling a switch by receiving Control Signal from SCADA, provides Distribution
Automation and minimize a fault area.

IEC60870-5-104
IEC 60870-5-104 (also known as IEC 870-5-104) is an international standard,
released in 2000 by the IEC (International Electrotechnical Commission). As can be
seen from the standard's full designation 'Network access for IEC 60870-5-101
using standard transport profiles', its application layer is based on IEC 60870-5-
101. IEC 60870-5-104 enables communication between control station and
substation via a standard TCP/IP network. The TCP protocol is used for connection-
oriented secure data transmission.
