Can you protect the distribution line out going from single phase transformer from electricity thefting?

The wires coming out of distribution Transformers are either kept high above the ground or underground; first for safety, second to deter energy theft.

How electricity gets from the generating plant to an appliance in a home?
through: wires, transformers, breakers, switches, etc.Something like:Power plant wires carry electricity to plant switching farm.Switches in switching farm direct electricity to step-up transformer for a transmission line.Step-up transformer increases voltage to reduce transmission losses.Wires from step-up transformer go to high voltage breaker to protect switching farm from transmission line current spikes.Transmission line wires attach to breakers and leave plant switching farm.Transmission line wires run hundreds of miles to consumer locations.Transmission line wires enter a distribution switching farm and attach to high voltage breakers to protect switching farm from transmission line current spikes.Wires from breakers go to step-down transformer to decrease voltage for safe distribution.Wires from step-down transformer go to switches in switching farm.Switches in switching farm connect electricity to desired distribution lines.Each distribution line has breakers on it to protect the switching farm and the line.Distribution lines run to various neighborhoods.At each customer location the distribution line connects to a step-down transformer to reduce the voltage to what the customer needs (e.g. U.S. residential 120V/240V 2phase).Wires connect the step-down transformer to the customer's fuse/breaker box and distribution panel.
What position in the circuit is a fuse placed to protect a transformer?
In series to every phase winding of transformer.
Will REF protect the outgoing cables when the Ct's are fitted at the transformer?
REF protection, when installed and set correctly, will protect everything within the CT's. If the CTs are on breakers, then yes, the cables from the transformer to the breakers will be in the zone of protection. If the CTs used are in the bushings of the transformer, then no.
Does the fuse on the primary side of a transformer protect the secondary side?
Yes, but it's usual to have fuses on both sides of the transformer.
Can you have two different size load wires that is unprotected on a transformers load side?
It is not a recommended practice. The secondary side of the transformer should go to a distribution panel where breakers can be used to protect the different wire sizes and load currents.
What piece of equipment is used to protect the technician from a potential fatal shock when working on hot chassis products Circulation transformer Isolation transformer Steppe transformer?
circulation transfomer circulation transfomer
What is the main purpose of earthing in 10 kva distribution transformer?
To protect the secondary winding from an interwinding fault. In the event of such a fault, an earth fault is detected by the high-voltage protection system, which interrupts the h.v. supply to the transformer. The tank is (separately) earthed for the same reason. The secondary earth also acts to provide the neutral connection to the l.v. system.
What is mov capacitor?
A capacitor used to protect the transformer if these any problem in the cct.
Is a rubber band a good conductor of electricity?
No, rubber is not a good conductor of electricity. Rubber is used to protect against electricity.
What is the purpose of the oil in a oil filled transformer?
cooling Not only that, but also to protect the windings from moisture.
What is the ratings for a pole fuse?
There are two types of pole-mounted fuse. One type is a high-voltage fuse, intended to protect the transformer. The other type is a low-voltage fuse, intended to protect the cable or line supplied by the secondary winding of that transformer. The current ratings of these fuses depend entirely on the current ratings of the devices they are there to protect.
Does the secondary feeder of a transformer need to be rated at less than the main breaker of the feeder supply panel?
It depends on the situation and how you are utilizing the transformer. Under certain conditions the secondary does not need to be protected. The protection on the primary is enough to protect the secondary side of the transformer.
