Protection and Monitoring of Horizontal and Vertical Busbars

Over the past 20 years, there has been a significant increase in the design and construction of high-rise buildings in both Israel and industrialized countries, a trend driven by the high demand for housing in limited spaces. These buildings include residential towers, office skyscrapers, hospitals, hotels, and more. The electrical infrastructure in such buildings is highly complex, consisting of multiple power sources and numerous consumers. This complexity often requires engineers to run numerous electrical cables through a vertical shaft in the building, occupying substantial space on each floor.
 

The Solution:

Installing busbars from the transformer to the main distribution board, and vertical busbars (often more than one for different fields) from the main distribution board to the various f loors, offers a highly effective alternative. Dedicated connection elements allow consumers on each floor to connect seamlessly to the busbars.

Key Advantages:

• Space-saving design
• Elimination of magnetic fields
• Flexibility for future connections and modifications via dedicated elements

The Problem:

The main drawback lies in the difficulty of performing preventive maintenance on these busbars, leading many building owners to avoid it altogether. However, if the installation is not executed precisely according to the manufacturer's guidelines, if the design is flawed, or if there are manufacturing defects, the result can be catastrophic. A failure in the primary electrical supply line to consumers can cause severe operational disruptions, incur significant financial costs for repairs, and in some cases, parts required for the repair may not be readily available, further compounding the damage and downtime.

Our Solution:

The GES system, enhanced with the HP10.4 module, is installed on the main distribution board and performs comprehensive quality checks for the busbars, including:

• Continuous resistance measurements of electrical connections on all three phases and the main neutral
• Current and voltage measurements
• Voltage drops
• Current and voltage harmonics
• Overloads, and more

This thorough monitoring allows the GES system to detect electrical faults in the busbars at very early stages. The system immediately notifies the user with details of the fault, its exact location on the busbars, and its severity level, enabling efficient intervention and preventing significant future damages.
