New Power Supply and Modification Projects for Domestic and Business SectorsJuly 13, 2018
Electrical connections can be seen hooking homes and businesses to the grid all over Australia. That network, constructed from over 5000 kilometres of cable, branches and subdivides, but the lines don't actually stop until they arrive at a local substation. Here's where a seasoned electrical contractor takes over. Tasked with linking the gap between this power-distributing node and a domestic neighbourhood, the first trench is going in right now.
New Neighbourhood Power Supplies
Just like the step-down design used in a developed nation's grid, a new power supply, one that's intended as a home electricity link, moves downwards in output as it travels into a home. The trench enters the property, a wire-armoured cable, coated in double-insulated rubber or plastic, enters a central electrical distribution board, and the cables reduce in size once more as they snake their way out of a fuse board. Incidentally, wire fuses are mostly a thing of the past because of resettable circuit breakers. Containing no more than three or four conductors, the wiring delivers 240-Volts of power, which splits at the distribution board, before it heads off to the various lighting circuits and plugs on the property.
Installing Business Sector Power
Here's a harder project, one that requires a group of electrical technicians and engineers who are up to the job. This time around, the distribution board occupies an entire room. Also, instead of a 240-Volt single-phase system, there's three-phase 415-Volt cabling entering the larger building. And, since this imaginary structure occupies several floors, busbars are travelling inside a trunking system. As the metal rods travel up the building, the office floors take "tappings" from the bars, and those linkages enter yet another distribution board, one that provides power to each individual floor.
Modifications and Regulatory Restrictions
An older home has just gained an extension. Meanwhile, down in the business district, a flourishing company is expanding to deal with the demands of success. As each building's electrical capacity increases, the system starts to experience a power overload. Modification projects often cause such problems. The building is still occupied, and the circuit breakers are tripping every time someone puts on a kettle. Maybe the substation switchgear needs upgrading, or it's the cables that need a high-diameter boost. Then there are circuit breakers in distribution boards to replace, cable resizing issues to solve, and much more.
What does an electrical contractor do before he rips up pavements and roadways? There are loading measurements to take in the building. Material costing charts also require attention. Then, tying it all together, there are volumes of regulation-packed books to pore over. They help with transformer upgrades, load discrimination, and every other project-relevant installation factor.
