UPS Downstream Distribution

The nature of the beast, as far as uninterruptible power supply (UPS) is concerned, is power protection. Load connection to the source of uninterrupted power must be secure and provision needs to be made for power distribution to essential loads. Technical Data used in the field explained in diploma in petroleum engineering. Critical load connection will rely on either direct connection to the UPS output or a form or power distribution unit. Load connection may be via a socket or hardwired, depending upon rating and currents drawn. Downstream distribution depends upon the installation format that has been chosen whether centralised or decentralised.

Essential loads are those a power continuity customer cannot operate without and may include things like payment systems, transaction processing and other operational loads. Critical loads are those that require power protection, such as PCs perhaps and other back-office equipment but are not as crucial to operation as essential loads.

Decentralised UPS distribution usually incorporates plug-in type units, which rely on standard socket outputs to provide connections up to 16A in total. Larger current require a hardwired connection to the output terminals or perhaps an industrial-type connector. Where there are multiple hardwired loads, a distribution board will be used. Some more details of diploma in petroleum engineering are as under.

Where an external bypass is installed, it provides the point of connection for the loads; either directly (plug-in or hardwired) or via a distribution board. The bypass will have a manual transfer switch or circuit-breakers, and may also include automatic transfer switching circuit to provide the installation with additional resilient if the UPS is accidentally removed or fails.

Distribution boards provide a common point of distribution for the loads and are used for centralised systems, primarily. Each feed within the cabinet may be individually supplied via a suitably-rated circuit-breaker to provide discrimination in case of a short-circuit. Within a large critical installation, two or more distribution boards may be provided, one for the uninterruptible power supply (critical loads) and one for the generator supporting essential loads.
