Uninterruptible power supply in and out of the switchboard

An Uninterruptible Power Supply (UPS) is defined as a piece of electrical equipment which can be used as an immediate power source to the connected load when there is a failure in the main input power source. In a UPS, the energy is generally stored in flywheels, batteries, or super capacitors.

The Core Function of a UPS: At its most basic, a UPS provides a continuous source of power to connected devices, even during power outages. It achieves this by storing energy in batteries and converting it to AC power when the primary power source fails.

In this project, the design of Low Voltage Main Switchboard for Marine Hub Logistic building covers the electrical loads such as lighting, power point, Air Conditioning system, Lift system, mac

This type of UPS, also known as Standby UPS, offers basic features. The primary power source is the filtered AC mains. When the power breakage occurs, the transfer switch will select the backup source (shown in dashed path in figure 1). Thus we can clearly see that the stand by system will start working only when there is any failure in mains.

Inside the switchboard is a bank of busbars generally wide strips of copper to which the switchgear is connected These act to allow the flow of large currents through the switchboard, and are generally bare and not insulated. Power to a switchboard should first be iso

Once the power is restored, the rectifier begins to charge the batteries. To prevent the batteries from overheating due to the high power rectifier, the charging current is limited. During a main power breakdown, this UPS system operates with zero transfer time.
