What Is The Requirement Of Lighting Transformer In Electrical System

describe:

1. your light (what is printed on the box),

2. available electrical system that will provide power.

A transformer is used to match these requirements or to provide a galvanic insulation to protect the man with the light from electrocution.

What happen if we did not install and directly give power to lighting load?

Try it and tell us afterwards or explain your materials now. There are many different light sources. Some require a transformer, or a ballast, or a electronic power supply, others don't.

But management would get jealous if they had competition relating to that and keeping the employees in the dark.

Something about mushrooms. Still working on it....

...and people would be using candles or bumping into things...

Using candles while bumping into things in the dark can be considered a fire safety hazard. It is recommended that in the event of a great darkness descending, due to incompetant power application, the use of battery operated lanterns be implemented.

Ensure that the battery operated lanterns are purchased from a store, specifically a different designer than whoever is responsible for improperly connected lighting.

What a brilliant idea.

Then someone is either going to get a stern repremand or fired.

Suppose you've got 120Volts AC mains, and, a light which requires a 12 Volt DC supply.

You'd use a "transformer" to convert the mains voltage into a voltage suitable for your light.

_{Psssst! And a rectifier to convert the wobbles from one shape to another - just sayin'.}

Lighting transformer is used in the Electrical System to avoid switching Spikes in Lighting Circuit,

These Switching spikes will lead to failure of the lamps.

What is a lighting transformer to you? Give a practical example please. See the previous post - that can be an application for a transformer when 12 Volts AC is needed per example for halogen spots. Special lights work with specific equipment like ballasts or electronic gear. Please help us solve your spikes mystery too.

Can you make us happy with a picture of such? Otherwise we need to accept an invitation to go study crops and have a peek at it there. I googled lighting transformer without success into your direction. But we all want to learn.

Sorry I could not clearly understood your mail. Are you suggesting to put pictures of Pole mounted Distribution Transformers? I do not have any of US but of India I can click one located at 20meters from my house. It will only draw criticism of domestic power distribution in my country as it is unsafe installation to any standards.

In US I noticed these are safely installed at a good height just below the cross arm of 13.8kV lines, safe and neat installation and LA installed before the transformer.

To start off... "Lighting Loads" are the loads that are presented to the installed electrical system by the system of illumination in a given area.

If you do not provide for those loads, the lights do not work.

Why would you use a "lighting transformer"?

All transformers change a voltage level from one level to another.

If the installed electrical system in a given building, or area of that building, does not support the voltage level needed for the type of lighting equipment you want to use, you need to transform the available power to a voltage level that meets your need. You do this with a transformer.

For example... many many years ago, when I started in my profession, the plant I was working at was a 230 volt corner grounded three phase delta system. To handle lighting and other single phase loads in the facility... the designers elected to install 3 x 112.5 kVA single phase transformers to handle those lighting and single phase loads.

These transformers had 230 volt primaries and a 230 volt center tapped secondary (which was also grounded), which gave us 2 x 115 volt sources to use for the lighting and other single phase loads in the facility.
