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,anomalies,and other events that may damage the transformer and initiates appropriate protective measures.

　　trait

　　High-speed operation,can quickly detect and respond to transformer failures

　　Multiple protection elements for transformer integrated protection

　　Advanced communication features for remote monitoring

　　User-friendly interface for easy configuration and operation

　　Robust 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 of transformers.

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

　　GE Multilin’s 745-W2-P5-G5-HI transformer protection relays protect and manage transformer systems to extend transformer life expectancy and optimize transformer performance.The device is a high control power supply version of the 745,accepting 90 to 300 V DC control power input;70 to 265 volts AC.The relay provides a number of practical functions for transformer systems,including over field blocking,over/under frequency protection,limited ground fault protection and system overload protection.Relays can monitor and effectively respond to changing system variables such as temperature or current.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 act as a standalone unit or a component in a larger array.

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

　　The RS232 port on the front panel of the relay is ideal for connecting directly to a computer to monitor a single relay.

　　The RS485/RS422 port is located on the rear panel of the relay and is ideal for direct connection to monitor multiple relays.

　　Ethernet,best suited for non-direct connection to relays.(Note that this feature is optional and only included in 745 models with a”T”in the model number-potential buyers should purchase one of these if an Ethernet connection is required.)

　　Once the preferred connection method is properly established,the EnerVista 745 allows users to monitor the system and edit setpoints with relative ease,especially compared to manually entering them via the relay’s front keyboard.In the EnerVista 745 program,the user can examine various measurements within the transformer system and also trend the data for further analysis.

　　Application field

　　The SR745-W2-P5-G5-HI GE high-speed transformer protection relay is suitable for transformer protection systems in power,petrochemical,metallurgy and other fields,as well as other sites requiring high-speed response and accurate monitoring.
