3BHB004661R0101 ABB Central control module

Product Description

The ABB High Impedance Protection Relay is a type of protection relay that is used to protect transformers, generators, and motors from earth faults. It is based on the principle that the impedance of a fault 

is much higher than the impedance of the protected equipment. This allows the relay to distinguish between internal and external faults.

Product Features

• High sensitivity: The ABB High Impedance Protection Relay is very sensitive and can detect even small earth faults.

• Fast operating time: The relay has a fast operating time, which helps to minimize damage to the protected equipment.

• Selectivity: The relay is selective, which means that it will only operate for faults in its protected zone.

• Reliability: The relay is a reliable and robust device that is designed to withstand the rigors of industrial applications.

Product Benefits

• Reduced downtime: The ABB High Impedance Protection Relay can help to reduce downtime by quickly clearing earth faults.

• Improved safety: The relay can help to improve safety by preventing damage to the protected equipment.

• Reduced maintenance costs: The relay can help to reduce maintenance costs by preventing the need for frequent repairs.

Considerations

• Application: The ABB High Impedance Protection Relay is not suitable for all applications. It is important to carefully consider the specific needs of the application before selecting a relay model.

• Setting: The relay must be properly set to ensure that it operates correctly. This requires careful consideration of the system parameters.

• Maintenance: The relay must be properly maintained to ensure that it continues to operate reliably. This includes regular testing and calibration.

Product Applications

The ABB High Impedance Protection Relay is a versatile product that can be used in a variety of applications, including:

• Power transformers: The relay is commonly used to protect power transformers from earth faults.

• Generators: The relay can also be used to protect generators from earth faults.

• Motors: The relay can be used to protect motors from earth faults.

Overall, the ABB High Impedance Protection Relay is a reliable and effective solution for protecting transformers, generators, and motors from earth faults. It is easy to use, has a fast operating time, 

and can help to reduce downtime, improve safety, and reduce maintenance costs.
