特点：

Features:

Comprehensive protection features:

Differential protection can detect internal short circuits in windings.

100% stator grounding protection, used to detect grounding faults in stator windings.

Grounding direction overcurrent protection, identifying and isolating grounding faults.

It may also include protection against overload, under load, unbalanced load, frequency deviation, voltage fluctuations, etc.

Measurement and monitoring:

Real time monitoring of generator parameters such as current, voltage, power, frequency, and temperature.

Provide data and event records for easy fault analysis and maintenance.

Communication capability:

Usually equipped with RS232 or other types of communication ports, allowing connection to SCADA systems or other monitoring devices.

Can send real-time data, receive remote instructions, perform configuration and debugging.

User interface:

LCD display screen, displaying system status and alarm information.

The user interface is user-friendly, simplifying the setup and fault diagnosis process.

Environmental adaptability:

Capable of operating within a certain temperature range and humidity conditions, but it is important to note that extreme conditions may affect equipment performance.

Flexibility and configurability:

Protection settings and functional configurations can be adjusted according to specific application requirements.

Notes:

Storage and working temperature:

Ensure that the ambient temperature for device storage and operation is within the specified range to avoid damage to the LCD display due to low temperature.

Humidity and altitude:

Maintain the equipment under non condensing humidity conditions and consider the impact of altitude.

Power requirements:

Confirm the voltage range of the DC or AC power supply based on the specific model to avoid unstable power supply or exceeding the range.

Maintenance and calibration:

Regularly inspect and maintain to ensure the accuracy and reliability of the relay. Perform regular calibration to maintain measurement accuracy.

Installation and wiring:

Follow the manufacturer's instructions for installation and correctly connect the current transformer (CT) and other sensors.

Ensure that all wiring complies with electrical specifications and safety standards.

Software updates:

Regularly check for firmware or software updates to enhance functionality or fix potential issues.
