From $3,947.00Sale Price
ACREL Medium Voltage Protective Relay - Feeder, Motor & Transformer Protection is a medium-voltage microcomputer protective relay for user substations with input voltage of 35 kV or above. It combines measurement, electrical protection, control and communication functions, with support for applications including feeder, transformer, motor, capacitor and bus tie protection. Depending on the selected model, the relay provides different protection functions, digital inputs and outputs, plus RS485, RS232 and GPS interfaces.
Quantity

The ACREL Medium Voltage Protective Relay - Feeder, Motor & Transformer Protection is designed for protection and control applications in medium-voltage user substations. Acrel specifies the AM5SE series for substations with an input voltage of 35 kV or above.

The relay combines electrical measurement with protection, control and communication functions. This allows key operating parameters to be monitored while configured protection functions can respond to abnormal electrical conditions.

The series covers several model configurations. AM5-F, AM5-T, AM5-M, AM5-C, AM5-B, AM5-U and AM5-BL have different combinations of protection functions and hardware resources, so the exact model should be matched to the intended application.

How it works

  • The relay receives voltage and current signals from the electrical system.
  • It measures parameters including RMS current, RMS voltage, frequency, power factor and RMS active power.
  • Configured protection functions monitor the electrical conditions for faults or abnormal operating states.
  • Depending on the model and protection scheme, the relay can provide alarms, trips and control functions.
  • Digital inputs and outputs allow the relay to interface with switchgear and other control circuits.
  • RS485, RS232 and GPS interfaces provide communication and timing capabilities.

Why choose this product?

  • Combines measurement, protection, control and communication in one protection device.
  • Multiple model configurations allow the protection functions to be matched to different substation requirements.
  • Suitable for feeder, transformer, motor, capacitor and bus tie protection applications.
  • Provides local and remote control capabilities.
  • Includes multiple communication interfaces for integration with monitoring and control systems.

Benefits

The ACREL Medium Voltage Protective Relay - Feeder, Motor & Transformer Protection can help centralise protection and electrical monitoring within a substation control arrangement. Its combination of measurement, protection and control functions can reduce the need for separate devices for individual functions, depending on the system design.

The range of available models also allows engineers to select a configuration appropriate to the required protection scheme rather than applying the same protection functions to every installation.
