Automatic Transfrer Switch using 8 pin Relay

This diagram shows an 8-pin relay connection ats. The terminal connects to the device to power when the relay receives no power. Mini contactor relays are used in the ATS implementation examples of power supply configurations with a priority source or with the option to select the priority source. In this diagram, we want to show a perfect connection ats (Automatic Transfer Switch) using a relay in the grid and generator line. You can follow this circuit diagram to gain knowledge of how to connect ats (automatic transfer switch) using 8 pin relay.

Components used to make the Automatic Transfrer Switch using 8 pin Relay:

01. Single Phase Energy Meter

Fig 2: Single Phase Energy Meter

The measuring device with the help of which the electric power or energy of a circuit is measured is called Energy Meter (Energy Meter). Also called a watt-hour or kilowatt-hour meter. For home appliances, we used a single-phase energy meter. The single-phase energy meter is directly connected between the line and the load. Both coils produce their magnetic fields, when the meter is connected to the supply line, and the load. Energy meters are used in homes and in industrial applications where we want to found that how much energy is being consumed by home appliances and electrical equipment.

02. Magnetic Contactor

Fig 3: Magnetic Contactor

A magnetic contactor is an electrical device used for load control, automation, and protection. It is much like a magnetic reel. However, relays are generally used for low power and voltage, on the other hand, when we think of high power, these heavy-duty contractors only come to mind. It basically works by switching the load on and off. It has 3 terminals whose inputs are denoted as L1, L2, L3, and outputs as T1, T2, and T3. The circuit of the load is made in automation mode or protection using auxiliary contacts. It has two types of terminals. 1) Normally Open (NO). 2) Normally Closed (NC).

03. DP MCB

Fig 4: DP MCB

Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

04. 8 Pin Relay

Fig 5: 8 Pin Relay

This relay is known as 8 pin relay because it has 8 terminals. When coil power is supplied. A magnetic induction is created due to which the connected sheet of the Com part moves towards the NO part changing to NO-NC. The former NC region loses conductivity and becomes NO. Thus, as long as power is supplied to the coil, the NO and NC positions will remain in the alternating state, and when the power is removed from the coil, it will return to its original position. This is basically how a relay switch works.

05. Power Generator

Fig 6: Power Generator

The Power Generator Is a Device That Converts Motive Power (Mechanical Energy) or Fuel-Based Power (Chemical Energy) Into Electric Power for Use in an External Circuit. In Addition to Electromechanical Designs, Photo Voltaic, And Fuel Cell-Powered Generators Utilize Solar Power and Hydrogen-Based Fuels, Respectively, to Generate Electrical Output. The Reverse Conversion of Electrical Energy Into Mechanical Energy is Done by an Electric Motor, And Motors, And Generators Have Many Similarities. Many Motors can be Mechanically Driven to Generate Electricity; Frequently They Make Acceptable Manual Generators.

Frequently Asked Questions

How does an automatic transfer switch work?

The ATS monitors voltage and frequency to verify acceptable power, then transfers the load. If the ATS does not detect an acceptable power supply, no transfer occurs because this action would not improve power availability to loads. Doing so would leave loads isolated from the normal of the source should acceptable power return.

What are the two types of automatic transfer switches?

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

What is the difference between a transfer switch and an automatic transfer switch?

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

How do I size an automatic transfer switch?

For service disconnect of the switches, the amperage must match that of the main breaker in your electrical panel, (it is usually located at the very top of the box.) So, if you have a 200-amp main breaker, you will need a 200-amp automatic transfer of the switch.

Advantage: Ideal for efficiently switching to generator power?

Beyond the necessity of maintaining a constant electrical supply, an automatic switch offers the most efficient way to change from utility feed to generator feed. Instead of locating manual switches after the lights go out, businesses could let the changeover happen automatically, the only scenario that wholly exempts a building from the noticeable effects of a power supply outage, allowing the business to carry on as before.
