产品描述

750-P1-G1-S1-HI-A20-R-E,SR-750 FEDER是GE SR继电器系列中的GEMultilin继电器(与GE Multilin 469电机保护继电器GEMultilin 735馈线保护继电器属于同一系列。） 489-P5- LO -A20-E专为发电机保护而设计，可用于感应或同步发电机。该装置i以在25、50或60赫兹下运行。

750-P1-G1-S1-HI-A20-R-E,SR-750FEEDER设计有40个字符的显示屏，允许用户查看值消息、诊断和设置点。前面板包括数字键盘、状态指示灯、数值上下键、RS232端口接口以及控制和编程键，包括复位、输入、菜单、菜单向上和菜单向下键。这允许在不连到外部计算机的情况下进行控制。

后面板包括十二个RTD输入、六个输出继电器、两个RS485通信端口和四个VT输入。RTD是现场可编程的。通信端口可以使用ModbusRTU 或DNP 3.0协议(或两者)，最高可达19200 bps。

虽然配电馈线系统管理可能是一项艰巨的任务，但通用电气Multilin的750-P1-61-S1-HI-A20-R简化了流程并延长了系统寿命。Multilin的馈线管理继电器配备了保护配电馈线系统的众多功能，通过其计量和数据记录功能减少了系统组件的压力，并减少了故障排除时间。

继电器的前面板分为大约四个部分:40个字符的液晶显示屏、键盘、LED和RS232端口。40个字符的液体显示屏是字母数字，在不使用时指示各种系统值(可由用户配置)，键盘允许手动配置设定点和继电器的一般导航。当系统中出现问题时，LED可以指示，并让用户了解活动过程。最后，RS232端口允许在运行EnerVista750软件的计算机和继电器之间轻松、直接地连接。

750-P1-61-S1-HI-A20-R包括计显功能，可以确定电压、频率、瓦时成本、负载跳间百分比以及运行和最大需求等值。继电器可以使用其计量功能在超过断路器维护阈值时触发警报。警报可以通过继电器的上述20个LED指示。

可以通过密码保护实施额外的安全措施，以防止未经授权调整设定值。此密码保护既适用于从继电器前端进行手动编辑，也适用于通过EnerVista 750程序进行编辑。要手动输入设定值配置，必须在后端子上安装跳线。

Product description

750-P1-G1-S1-HI-A20-R-E,SR-750 FEDER is a GEMultilin relay in the GE SR relay family (the same family as the GEMultilin 469 motor protection relay GEMultilin 735 feeder protection relay). The 489-P5-LO-A20-E is designed for generator protection and can be used in induction or synchronous generators. The device i is designed to operate at 25, 50 or 60 Hertz.

750-P1-G1-S1-HI-A20-R-E,SR-750FEEDER has a 40-character display designed to allow users to view value messages, diagnostics, and setting points. The front panel includes a numeric keypad, status indicators, numerical up and down keys, RS232 port interfaces, and control and programming keys, including reset, input, menu, menu Up, and menu Down keys. This allows control without being connected to an external computer.

The rear panel includes twelve RTD inputs, six output relays, two RS485 communication ports, and four VT inputs. RTDS are field programmable. Communication ports can use ModbusRTU or DNP 3.0 protocols (or both) up to 19200 bps.

While distribution feeder system management can be a daunting task, GE Multilin's 750-P1-61-S1-HI-A20-R streamlines the process and extends system life. Multilin's feeder management relays are equipped with numerous features to protect distribution feeder systems, reduce stress on system components and reduce troubleshooting time through their metering and data logging capabilities.

The front panel of the relay is divided into approximately four parts: a 40-character LCD display, keyboard, LED, and RS232 ports. The 40-character liquid display is alphanumeric, indicating various system values when not in use (user-configurable), and the keyboard allows general navigation of set points and relays to be manually configured. When there is a problem in the system, the LED can indicate and let the user know the activity process. Finally, the RS232 port allows for an easy and direct connection between a computer running the EnerVista750 software and the relay.

The 750-P1-61-S1-HI-A20-R includes a meter function to determine voltage, frequency, watt-hour cost, load hop percentage, and operating and maximum demand equivalents. The relay can use its metering function to trigger an alarm when the circuit breaker maintenance threshold is exceeded. The alarm can be indicated by the above 20 leds of the relay.

Additional security measures can be implemented through password protection to prevent unauthorized adjustments to set values. This password protection is suitable for both manual editing from the relay front end and editing through the EnerVista 750 program. To manually enter the set value configuration, a jumper must be installed on the rear terminal.

Frequently Asked Questions about 750-P1-G1-S1-HI-A20-R Whether the control power supply should be followed by GE feeder management

How many output relays does GE feeder Management relay have?

750-P1-61-51-HI-A20-RGE feeder management relays have eight (8) output relays. The 8 output relays have configurable auxiliary relays between 3 and 7. The 1 and 2 relays are tripping and closing output relays, while all 8 relays are self-check warning relays.
