Goodluck on this YT Channel! nice presentation

Your definition of radial system is different than mine. On my radial system the primary line dead ends and if you loose the line all of the customers on that line are out. The next system is a loop system is when you have the line fed from more than 1 source or the line ties back into the same source. The last system is like you said a network system where not only can the primary be looped, but the secondaries of transformers are in parallel so if you loose one transformer the others carry the load. The only place that I am aware of that runs a network system is Toronto.

شكرا على الشرح thanks for your explaination.

How do I calculate the normal load current in a ring main system?

Nicely Explained

Thank you sir!!!!!!!!!!

Interesting point about the huge available fault current on a network system. What scenario would typically require transformers being paired on a network system? Would this be reserved for hospitals and critical operating systems? Also, wouldn't most network systems be set up with a main tie main application in order to shut down a faulted section and prevent the huge available fault current?

" Would this be reserved for hospitals and critical operating systems?" Definitely not. In well developed countries this is quite common in cities. This is how "we keep the lights on 99.99999...% of the time. Depending on the density of the city there may be 3 transmission substations within 5 miles each with several transformers bringing transmission down to distribution voltages. This pretty much insures the electricity is on almost without interruption. This is also why developed countries typically pay much more for the convenience of electricity.

Is Ring main system is same as network system?

[@ZackHartle]

Very similar. The ring system just connects again at the ends so if the main line breaks, there's no loss in power

[@randallmartin2549]

Not quite right. The network is fed from multiple primary circuits, so if a fault occurs on one of the primary circuits, the network protectors on that circuit will trip. But the other NP’s on different circuits will stay closed, so no loss of power to high rise buildings.

Distribution is a complicated issue .radial vs network .What they call networked should be called poly nodal power distribution .Yes it's a form of network but it's a poly nodal system and creates a huge problems in the event of failures .The advantage is that if there is a failure once the failure is isolated the rest of the system can remain energized .With this so called green energy systems coming in you are going to have many issues .One issue is of the power produced from being pumped back into the network in a fault condition causing many issues .There needs to be a means of disconnecting the power nodes from the network in the event of a fault condition ,or reconnection of the node to the network to supplement the network demands . There needs to be a reliable interconnected communication system between all the micro power plants and the network and main power plants .
