GE Multiline™ 345 3 Series Protective Relays

The 345 provides excellent accessibility and transparency of power system conditions and events through its target information and four-line, 20-character display, transient and event recorder.

and the powerful EnerVista PC programme.

Easy-to-use drawer and non-drawer configurations The 345 is available in both drawer and non-drawer configurations.

The drawer chassis design345 simplifies installation and improves field safety, such as the need to rewire equipment after opening a switchgear door or cancelling a test.

Like communication cables stay connected even when the relay is withdrawn, communication status is retained.

The 345 Protective Relay Chassis is used in conjunction with the pull-out relay which is available separately as a partial replacement or in a test environment.

This pull-out relay without chassis can also be ordered as a spare unit.

Application flexibility and ease of wiring The available universal CT inputs as well as the software configurable input ranges (1A and/or 5A) help to standardise the design and reduce the number of order codes.

There is also no need to change the entire design in case of relay changes or future switchgear modifications.

Mixed inputs of 1A or 5A favour ground CTs for different applications from phase CTs. easy to remove terminal wiring and in-system testing or troubleshooting.

Easily retrofitted compact and withdrawable Function 345 relays minimise installation requirements and enable easy retrofitting of existing cases.

As well as allowing side-mounting of multiple relays side-by-side on the panel. the 345 also offers pluggable RS485 and IRIG-B connections for easy troubleshooting.

Quick and Easy Configuration The 345 requires quick setup screens for standard transformers with minimal configuration protection applications.

With the powerful EnerVista 3 Series setup software, device configuration is accomplished in one simple step.

Advanced Communications Easily Integrate into New or Existing Infrastructures With a variety of Ethernet and serial port options, as well as multiple protocols offered by the 345

and flexible options for new communications as well as existing energy management, SCADA and DCS systems.
