Redundancy
System control is vital and an essential part of nearly all Switchgear, this being systematic, manual, automatic or an amalgamation of them all. However, before we can even start to consider what control we will implement we must first decide what we need to control and therefore the redundancy of the system.
There are various types of system redundancies and this is very particular to your exact requirements, typically when talking about the automation process the general relation is towards controlling main incoming devices and buscouplers ensuring redundancy. Therefore we first must understand what inputs are required and their backup requirements to keep the system running upon primary supply failure and maintenance. Typical system solutions have been derived below:
Focusing on particularly the input supplies of the switchboard, this is quite simply described as N. There are many combinations of solutions and it again is very dependent upon what your site requirements are, these inclusive of typically Transformer (Mains) and Generator inputs. These are described further below and typically detailed on your electrical schematics.
Please note for further advice on Manual / Automatic Control applications please follow this link (Expand-Click Me).
Above dictates a few typical redundancy systems but there are various alternative solutions that are again particular to your projects requirements and your desired application solution.
These solutions can vary from different redundancy types depending on the application.
