Cabinets and devices of relay protection and automation (RPA) manufactured by Radiy are a modern solution for control, automation, protection, monitoring and signaling at power facilities. They are used effectively in the following applications:

  • Power plants and substations
  • Electric grids
  • Electricity generators
  • Generator power transformer units
  • Power lines and other elements of power systems

This equipment is ideal for both newly constructed facilities and modernization of existing facilities, including the replacement of outdated panels.

Designation

Cabinets and panels (relay protection and automation) are specialized electrical complete devices that provide:

  1. Protection of power equipment.
  2. Automation of control processes.
  3. Control and monitoring of power grid parameters (rated voltage, current, frequency, power, etc.).
  4. Signaling of emergency events or abnormal operating modes.

Why do you need a relay protection and automation cabinet?

Relay protection and automation are important for ensuring stable, safe and reliable operation of power systems. This equipment detects emergencies in a timely manner and prevents damage to equipment, which avoids power outages. This is especially important for production.

How is it equipped?

Cabinets and panels can be equipped with up to 4 microprocessor terminals, operational control devices, testing/examination devices, alarms and devices for communication with automatic control systems. Design of cabinet and panel sets are independent of each other, having separate rows of clamps and controls.

Relay protection and automation panel: Areas of application

This is a critical equipment for the power industry, as it protects electrical systems from emergencies and ensures their reliable operation. The main areas of application for protection and automation relay include:

  • Energy (for detecting and disconnecting emergency areas in the event of a short circuit, overload or other malfunctions, protection of substations, automatic re-energization, automatic reserve introduction, etc.).
  • Industry (protection of production facilities, production automation (uninterrupted operation of complex equipment and processes).
  • Transportation (electrified railways, subways and urban electric transport).
  • Alternative energy (protection of wind and solar power plants, monitoring the stability of variable load systems).
  • Housing and utilities (protection of power grids in residential buildings, hospitals, office centers, automatic disconnection of emergency areas to minimize the consequences).
  • Military and defense industry (uninterrupted power supply to strategic facilities, protection of electronic control systems).
  • Smart grids (integration of automatic protection systems into modern smart power grids, optimization of energy consumption and reliability).
