1617137-3 type relay is a 3-pole voltage relay. It has the current transformer and a voltage relay sensor, which is used to monitor power system voltage.

This type of relay is widely used in power transmission and distribution lines, high voltage transmission lines, and other important power supply systems. It can detect changes in voltage and protect the power system from overvoltage or undervoltage. In addition, it can also detect ground faults, line disconnections, and other events that can endanger the stability of the power system.

The key component of this type of relay is the current transformer. It is used to measure the voltage. The current transformer changes the high voltage into the sensitive current and then the voltage value is displayed. The current transformer also determines the minimum or maximum voltage values and sends an alarm signal if the value exceeds the preset range.

Another key component is the voltage relay sensor. It monitors the input voltage on the power system and generates an output signal when the voltage exceeds a certain threshold. This output signal can be used to control the status of the system, such as trip command, power shutoff, or other actions. This type of relay is also used in motor monitoring and emergency awareness systems.

One of the main advantages of 1617137-3 type voltage relay is its ability to detect and respond quickly to changes in voltage. It has a wide range of settings for different voltage levels to fit different power systems. Furthermore, the compact design of this type of relay makes it easy to install in confined spaces.

In conclusion, the 1617137-3 type voltage relay is a reliable and versatile protection device used in many power systems. Its sensitivity and quick response time make it an ideal choice for protecting power systems. The current transformer and voltage relay sensor ensure accurate and timely detection of system voltage. The compact design makes it easy to install and maintain.
