Electric pole transformer

A distribution transformer or service transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. If mounted on a utility pole , they are called pole-mount transformers. Pole mounted transformers are electric utility distribution transformers that are mounted on an electrical service pole (wood or concrete) and are usually at the level of the overhead cables. Electric Pole Transformers - Duration:.

Whether stepping down for low voltage electrical equipment or creating a custom wiring project that requires a current transformer , today’s industrial and technology companies need transformers for a wide range of projects, and Grainger is ready to meet that need with these reliable products. Largest supplier of remanufactured and rebuilt transformers in the US! Specializing in rewinding and reconditioning power and distribution transformers , TR continues to make customer satisfaction its top priority. What is a pole transformer? Prolec GE designs and manufactures a complete line of single-phase pole-type distribution transformers for installation on utility overhead systems.

These highly reliable and cost-effective transformers are available in a wide variety of ratings and accessory combinations to match your system requirements. Transformers convert higher voltage electricity carried by primary wires and lowers the voltage for use by customers. Guy wires help stabilize utility poles.

A ground wire runs the entire length of the pole. It directs any electricity on the pole safely into the earth. A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.

Pole transformersusually range from kVA to 100kVA and transform 10to 30volts down to a low voltage of 4volts. Pole transformermodels are usually small in size to make them easy to install them on single pole structures, and larger units on two- pole structures. There are two things to notice in the pictures at left and right: 1) On the right, there are two wires running out of the transformer and three wires running to the house. Power transformers transform electrical voltage from one level or phase to another, usually stepping down voltage from a higher to a lower level.

A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works on the principle of Faraday’s law of induction by converting electrical energy from one value to another. You have likely seen the type of electrical transformers that sit on top of electric poles. These contain coils or windings that are wrapped around a core.

The power travels through the coils. The more coils, the higher the voltage. On the other han fewer coils mean lower voltage. These Three Phase transformers offer consistent, smooth voltage transformation at 480VAC input.

MODEL DESCRIPTION WT. Labor is often the largest cost. This type of transformer is called an “Impedance Transformer” and is mainly used for impedance matching or the isolation of adjoining electrical circuits.

The difference in voltage between the primary and the secondary windings is achieved by changing the number of coil turns in the primary winding ( N P ) compared to the number of coil turns on the secondary winding ( N S ).

Anecdotal information: After they extended development of the street I grew up on, we had the pole transformer at the head of the street fail several times. How big and how near are the questions.

Big transformers are usually connected to HV lines and they are actually the source for any magnetic fields you might be exposed to.
