Mains Distribution Systems and Mains Failure
Mains distribution systems vary from simple e.g a sub main supply for a garage, up to large London commercial or industrial projects requiring a reliable meshed system.
The simplest mains distribution network is referred to as a radial system. It is the cheapest and easiest to install. It’s down-side is that multiple users are affected by a mains failure fault, so it is only really practical on small applications where a mains power outage would not be critical. For example, in a hospital, a fault on a radial system would mean several areas would suffer a power outage. This can put lives at risk so a more ‘compartmentalised’ system would be needed.
One such system uses parallel feeders. This gives a greater reliability, however, since it is more complex, it is more expensive to install. Where the highest levels of reliability are required, the extra expenditure is essential.
Where costs justify the need, networks include built-in redundancy to make sure that there is always a route for the electricity, making them highly reliable.
New Switch Fuses
Sometimes, a power outage will be caused by the switch fuse. In commercial and industrial situations, this is usually connected to a 415 volt supply and needs a professional commercial electrician to investigate and repair the problem.
A domestic electrician is not used to working with three phase or high voltage mains supplies. We have over 25 years of experience in the field and out engineers are well-versed in with industrial high-voltage and three phase installations.
Where your switch fuse needs replacing, we will use the highest quality components for your budget e.g. the renowned Wylex switch fuse. These come with the standard values of fuse link and are made from steel in order to withstand the rigours of life in an industrial unit or factory.
