ACREL Intelligent Protection Relay for Power Systems is a medium voltage protection relay designed for electrical power system protection and monitoring. The series includes configurations for voltage transformer supervision as well as line, feeder and transformer protection, with protection functions such as overcurrent, earth fault, negative sequence overcurrent, overvoltage and undervoltage protection. It is suited to medium voltage switchboards and power distribution applications where dependable protection and configurable relay functions are required.
Quantity

The ACREL Intelligent Protection Relay for Power Systems provides protection functions for medium voltage electrical systems, with model configurations intended for different protection requirements.

The AM4 range includes AM4-U1 models for voltage transformer supervision and voltage protection, while the AM4-I configuration is intended for line, feeder and transformer protection. Acrel's published catalogue identifies functions including overcurrent, earth fault, negative sequence overcurrent, auto-reclose, overload, under-frequency, overvoltage and undervoltage protection for the AM4-I model.

The relay is suitable for integration into medium voltage switchboards and power distribution systems where electrical faults need to be detected and appropriate protection functions applied.

How it works

  • The relay receives electrical measurements from the connected power system and evaluates them against configured protection conditions.
  • Depending on the AM4 model, the relay can monitor voltage-related conditions or provide current and voltage-based protection functions.
  • When a monitored condition reaches the configured protection threshold, the relay can initiate the appropriate protection response.
  • Protection parameters and functions can be configured to suit the requirements of the electrical installation.

Why choose this product?

  • Provides dedicated protection functions for medium voltage power systems.
  • Available in configurations for voltage transformer supervision or line, feeder and transformer protection.
  • Supports a broad range of electrical protection functions on the AM4-I configuration.
  • Designed for integration into medium voltage switchgear and protection systems.
  • Provides a practical option for panel builders and electrical system integrators requiring configurable protection equipment.

Benefits

  • Helps detect abnormal electrical operating conditions.
  • Supports selective protection of medium voltage circuits and equipment.
  • Allows protection functions to be matched to the application.
  • Can be incorporated into switchgear and power distribution protection schemes.
  • Provides a dedicated relay platform rather than relying on separate individual protection devices.
