SR745-W2-P5-G5-HI GE High Speed Transformer Protection Relay

Product Description

The SR745-W2-P5-G5-HI GE high-speed transformer protection relay is designed to provide reliable and accurate protection for transformers.It detects faults,abnormal situations,and other events that may damage the transformer,and initiates appropriate protective measures.

feature

High speed operation,capable of quickly detecting and responding to transformer faults

Multiple protection elements for transformer comprehensive protection

Advanced communication features for remote monitoring

User friendly interface,easy to configure and operate

Durable and reliable design for long-term performance

The SR745-W2-P5-G5-HI GE high-speed transformer protection relay is a state-of-the-art device that ensures the safe and reliable operation of transformers.It combines advanced protection algorithms,high-speed operation,and extensive communication capabilities to provide comprehensive protection and monitoring for transformers.

GE Multilin’s 745-W2-P5-G5-HI high-speed transformer protection relay can operate in operating ambient temperatures ranging from-40F to+140F and can withstand up to 90%of unqualified humidity.The device can be comfortably stored at temperatures ranging from-40F to+176F.

GE Multilin’s 745-W2-P5-G5-HI transformer protection relay excels in protecting and managing transformer systems,extending the expected lifespan of transformers and optimizing their performance.This device is a high control power version of 745,which accepts control power input from 90 to 300 V DC;70 to 265 volts AC power.This relay provides many practical functions for transformer systems,including over excitation blocking,over/under frequency protection,restricted ground fault protection,and system overload protection.Relay can monitor and effectively respond to system variables such as temperature or current changes.The 745-W2-P5-G5-HI has 16 logical inputs and an expansion port array located at the rear of the terminal,which is highly configurable and can serve as independent units or components in larger arrays.

745-W2-P5-G5-HI includes the following options for connecting a computer running EnerVista 745 software program to the 745 transformer protection relay:

The RS232 port on the front panel of the relay is very suitable for directly connecting to a computer to monitor individual relays.

The RS485/RS422 port is located on the back panel of the relay,making it ideal for direct connection to monitor multiple relays.

Ethernet is most suitable for non direct connection to relays.(Please note that this feature is optional and only included in the 745 model with”T”in the model-if Ethernet connection is required,potential buyers should purchase one of them.)

Once the preferred connection method is correctly established,users can use EnerVista 745 to monitor the system and relatively easily edit settings,especially compared to manually entering settings through the relay front keyboard.In the EnerVista 745 program,users can check various measurement results within the transformer system and perform trend analysis on the data for further analysis.

application area

The SR745-W2-P5-G5-HI GE high-speed transformer protection relay is suitable for transformer protection systems in fields such as power,petrochemicals,metallurgy,and other places that require high-speed response and precise monitoring.
