Automatic Changeover Switch Wiring:

This diagram shows how to make Automatic Changeover Switch Wiring. In this circuit, we use two DP MCBs ( Double Pole Miniature Circuit Breaker ), two magnetic contactors, a single-phase energy meter, and a power generator. This circuit is very simple and easy to make, if you want to know more about this circuit please stay with our website and check our youtube video below the post.

Components used to make the Automatic Changeover Switch Wiring:

01.  Magnetic Contactor:

A magnetic contactor is an electromagnetic switching device. It is generally used for controlling 3-phase Motors. The operation of a magnetic contactor is similar to that of a Relay. but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil. its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.

02. DP MCB:

DP MCB In 2 Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls 2 Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control 2 Different Electrical Circuits at the same time, which allows the Appliances to Isolate safely and reliably. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches and Electrical components.

03. Single Phase Energy Meter:

A Single-Phase Energy Meter is a sort of Watt-Hour meter. It consists of two Electromagnets. Single-Phase Energy Meter is also Popularly known as a watt-hour meter. 1 Magnet is called the shunt magnet Ml which is Mounted with a Pressure coil. The Pressure coil is a long coil Made of fine Copper wire that is connected across the Supply single-phase line. Single-phase energy meters are suitable for measuring single-phase AC current flow frequencies of 50/60 Hz, which are used for fixed indoor installation systems.

04. Power Generator:

An electric generator is a type of Electrical device that converts mechanical energy or power into electrical energy or power. However, dynamo generally refers to generators only. The first generator built was called a dynamo. This electrical device makes this conversion using the principle of kinetic electromagnetic energy generation. According to Farad is principle of electromagnetic induction, a dynamic electromagnetic induction is induced in a conductor when it passes through a magnetic flux.

Frequently asked questions

What is the process of an automatic transfer switch?

To transfer loads between power supply sources, automatic transfer switches must (1) carry current flow continuously, (2) detect power supply failures, (3) initiate the alternate source, (4) transfer load to the emergency sources, (5) since the restoration of power supply to the normal source, and (6) retransfer load to the normal source.

What is the mechanism of the changeover switch?

Monitoring: The automatic changeover switch continuously monitors the power supply sources, checking for the restoration of the primary source. Once the primary source is stable and within acceptable parameters, the switch automatically reconnects the load to the primary source and isolates the secondary source.

What are the two types of automatic transfer switches?

There are two types of automatic transfer switches, circuit breakers and contactors. The circuit diagram breaker type has two interlocked circuit diagram breakers, so only one breaker is closed at any anytime.

What is the difference between manual and automatic changeover switch?

Unlike a manual transfer switch, automatic transfer switches can be used with permanently installed standby generators. That way, when your power supply is disrupted and your company is subject to blackouts, your generator will automatically kick on and supply an emergency backup power supply to your building.

What is 3 way switch?

A 3-way switch allows you to control a ceiling light (or other electrical fixture) from two separate locations. Common scenarios would be three-way switches located at both the top and bottom of the stairway or having three-way switches next to doors in a room with 2 entry points.
