MINILEC manufactures single-phase preventor and motor protection relays designed for monitoring the incoming three-phase supply from the mains (electricity distribution line) to protect motors from various electrical faults. Here's an overview of their functions and features: Single-Phase Preventor: This device is designed to monitor the incoming three-phase supply and detect any single-phase conditions, such as phase loss or phase unbalance. When a single-phase condition is detected, the preventor takes action to prevent the motor from starting or operating to avoid damage due to unbalanced voltages or currents. Motor Protection Relay: The motor protection relay is a comprehensive protection device that monitors various parameters of the motor, including voltage, current, phase sequence, phase unbalance, overload, and thermal conditions. It provides protection against faults such as overload, phase loss, phase reversal, phase unbalance, and overtemperature, thereby ensuring the safe and reliable operation of the motor. Functions: MINILEC's single-phase preventor and motor protection relays typically offer a range of functions and features, including: Overload protection: Protects the motor against excessive current flow that could lead to overheating and damage. Phase sequence monitoring: Ensures that the phases of the incoming supply are in the correct sequence to prevent motor damage. Phase unbalance detection: Detects and alarms or trips the motor if there is significant voltage or current imbalance between the phases. Under voltage and overvoltage protection: Protects the motor from damage caused by excessively low or high voltage conditions. Thermal protection: Monitors the temperature of the motor windings and trips the motor if it exceeds a preset threshold to prevent overheating. Communication interfaces: Some relays may include communication interfaces such as RS485 or Modbus for remote monitoring and control. Applications: These relays are commonly used in a wide range of industrial and commercial applications where motors are critical for operations, such as pumps, compressors, conveyors, fans, and HVAC systems.
