How do Backup Generators work?

Power outage is common around the world. But places that are prone to storms and heavy rain, see more power outages. It can be from one hour to several weeks. In such cases, a backup generator or standby generator comes into the picture. What is a standby generator or backup generator? A backup generator is … Read more

How Do Generators Make Electricity?

Generators are appliances used for power supply when there is a power outage to ensure activities continue as usual. Generators are a secondary electric power source in both industrial and residential use. Are you interested to know more about the generator? Read it here weldinghubs. Generator components Engine The engine is regarded as the main … Read more

Dot Convention in Transformer

The Dot convention is a type of polarity marking for transformer windings which describes the phase relationships in the transformer schematic diagrams. In this, the dots are mentioned on the primary and secondary windings of the transformer. By convention, the dot represents the positive polarity. Before we learn dot convention in transformer, first see the … Read more

Permanent Split Capacitor Induction Motor

In previous articles, we discussed different types of single-phase induction motors such as Split phase induction motor, Capacitor-start inductor motor, Capacitor-start capacitor-run induction motor, and Shaded pole induction motor. In this article, we will see another type of single phase motor i.e. Permanent Split Capacitor Induction Motor. It is also known as Permanent Split Capacitor Motor or … Read more

Capacitor Start Capacitor Run Induction Motor

A Capacitor Start Capacitor Run Induction Motor is a single phase motor consists of a stator and a single-cage rotor. The stator has two windings i.e. main winding and an auxiliary winding. The auxiliary winding is also known as starting winding. In construction, these two windings are placed 90° apart in space. This motor has … Read more

Difference Between 1-Phase & 3-Phase Induction Motor

The 1-Phase and 3-Phase Induction Motor is compared based on the factors such as power factor, efficiency, maintenance, supply, starting torque, applications, etc. Features 1-Phase Induction Motor 3-Phase Induction Motor Supply Works on 1-phase supply Works on 3-phase supply Starting torque Low High Power factor Low High Efficiency Less High Maintenance They are easy to … Read more

Methods of Starting of Synchronous Motors

Since synchronous motors are not self-starting inherently, we should have some means of starting synchronous motors. The methods are given below: 1. Induction Motor Start Damper windings, consisting of copper bronze bars embedded in slots in the pole faces and short-circuited at both ends are usually provided in synchronous motors which serve not only to … Read more
