Main disconnecting point (HRM)

Main Disconnect Device (HRM) is a device that serves to quickly disconnect electrical current from the distribution system. The main task of HRM is to ensure safe maintenance, repairs, or replacement of electrical equipment. This device is a key component of network protection, especially in solar panel systems, where it disconnects the production part of the source from the distribution system in the event of a fault or issues that could threaten network stability.

HRM is essential for the safe and reliable operation of electrical systems, particularly when renewable energy sources such as solar panels are used.

Maximum reserved capacity (MRC)

Maximum Reserved Capacity (MRC) is the highest amount of electrical energy that a consumer has contractually agreed upon with the distribution system operator and can consume at a given time.

At different voltage levels, the MRC is determined differently:

Very High Voltage (VHV) and High Voltage (HV): The MRC is the average value of the quarter-hourly active power agreed upon in the connection contract or specified in the connection conditions for a particular delivery point.
Low Voltage (LV): The MRC is determined by the ampere value of the main circuit breaker before the electricity meter or the converted kilowatt value of MRC to amperes, as agreed upon in the connection contract or specified in the connection conditions for a single delivery point.

The MRC ensures that consumers have sufficient capacity to meet their peak consumption needs without the risk of exceeding the capacity, which could lead to penalties or interrupted supply.

Measurement and regulation (MaR)

Measurement and Regulation (MaR) is a system that ensures the control and smooth operation of technologies at the delivery point, such as heating, ventilation, air conditioning, cooling, and lighting. This system takes care of comfort and safety, efficient management of technological equipment, operational monitoring, and energy consumption optimization.

MaR systems are essential for modern buildings and industrial facilities because they contribute to increased efficiency, comfort, and operational safety.

Micro-blackouts

Micro-blackouts, also known as micro-abortions, are brief interruptions in the power supply that usually last less than one second. These outages can be caused by a variety of factors, including distribution network problems, atmospheric influences, accidents, or rapid changes in electricity consumption.

Although micro-blackouts are brief, they can cause significant problems in sensitive electronic systems such as computers, data centers, or medical devices. Therefore, it is often necessary to use backup power supplies or power interruption protection systems to minimize potential damage or interruptions in operation.
