assuming a delta connected single phase transformers , why is the neutral side is connected to ground, my question is will the current be shunted to ground since it has a low resistance??? please explain
In order to have a neutral in a delta connected , 3-phase transformer bank, the secondary of the system must be connected in wye or star configuration. The neutral point is grounded in order to offer some protection in the event one of the hot leads is connected to some part of a device housing where you can touch the device. Electrical codes require electrical equipment to be grounded. If the hot wire does touch the chassis of a grounded piece of electrical equipment, the current will flow back to the transformers, causing the circuit breaker feeding the equipment to trip. This removes the danger to anyone touching the equipment. The reason there is no current flow in the ground under normal operation, is there is no connection from a hot lead to ground. There must exist a complete circuit in order for current to flow, TexMav
In electric distribution structures transformers are available countless sizes. Heavy ones are generally located on the floor with a concrete pad located under it to furnish help. those pad fastened transformers are risk-free against touch with the regularly occurring public generally with a fence. Pole fastened transformers are lighter and can be accurately located immediately on the skill pole. i don't comprehend of any floor fastened transformers different than for transformers located in vaults while the distribution strains are underground. yet those additionally desire some form of pad under them.
