About the project
As part of the modernisation project for Nehoiu Town Hospital, KRONTAB installed the low-voltage distribution infrastructure required to supply standard and critical consumers, as well as the installations associated with critical medical areas.
The solution comprises 50 switchboards, starting with the 1,600 A main distribution board and continuing with the distribution to critical loads, operating theatres, the intensive care unit, sub-distribution boards and the installations associated with the hospital’s various technical areas.
The system architecture was designed with a focus on power continuity, the functional separation of loads, and the provision of an alternative power source for critical circuits. A dedicated 1,600 A switchboard was installed for these loads, fitted with an ATS to enable automatic switching between the normal power supply and the generator set.
Through the scale and diversity of the switchboards installed, the project provides a modernised electrical infrastructure, tailored to the specific requirements of a medical facility where the availability of electricity is essential for the operation of equipment and the provision of medical care.
Benefits:
Built around the requirements of each project.
Control over the entire manufacturing process.
Equipment and systems from established manufacturers.
Every switchboard is inspected and tested before delivery.
Reliability designed for long-term operation.
Supplier of Equipment Used
Implemented solution
The Main Low-Voltage Switchboard is the primary distribution point of the installation and is configured with two 1600 A power sources and a 1600 A bus coupler.
The configuration allows flexible management of the main distribution system and separation of the installation into distinct sections, providing the possibility to transfer and redistribute the power supply depending on source availability and operating conditions.
The switchboard integrates the equipment required for protection, distribution, metering, control and signaling, and is designed for safe operation and efficient maintenance and technical interventions.
A dedicated 1600 A electrical switchboard was installed to supply the hospital’s essential loads, with two independent incomers: the normal power source and the generator set.
The ATS – Automatic Transfer Switch monitors the availability of the main power source and manages the automatic transfer to the backup source in the event of loss of the normal supply.
This configuration helps maintain power supply to installations and equipment considered essential for the operation of the medical facility, reducing interruption time and increasing the availability of the electrical infrastructure.
For medical areas with special requirements, 8 TSO electrical switchboards were installed for operating rooms and ICU areas.
The switchboards provide distribution and protection for the circuits serving these areas, where power supply safety and electrical system availability are particularly important.
The configurations were adapted to the loads and specific functions of each area, allowing circuit separation, clear identification and controlled operation of the electrical installation.
The secondary distribution system is implemented through a set of 40 electrical switchboards serving the different functional areas and technical spaces of the hospital.
These switchboards provide power supply and protection for the circuits associated with the specific loads in each area, linking the main distribution system to the building’s final installations.
By separating distribution according to areas and functions, the installation benefits from a clear structure, faster circuit identification and the ability to carry out technical interventions and maintenance work without unnecessarily affecting other areas of the hospital.
To optimize the operation of the electrical installation, a 300 kVAr automatic reactive power compensation bank was integrated.
The system adjusts the level of compensation according to the operating conditions of the loads, contributing to improved power factor, reduced reactive power flow and more efficient use of the electrical infrastructure.
The switchboards integrate the functions required for measuring and monitoring relevant electrical parameters, as well as for control and signaling of operating status where required by the installation configuration.
Monitoring these parameters provides a clearer overview of the electrical distribution system and helps quickly identify deviations or situations requiring intervention.
In a critical environment such as a medical facility, with a large and diverse number of loads, these functions contribute to efficient system management and continuity of operation.
