Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.

• Transformers have two coils of wire, known as the primary and secondary coils.

• When an alternating current flows through the primary coil, it creates a changing magnetic field.

• This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy.

• The ratio of the number...read more

Different types of sensors include temperature sensors, pressure sensors, proximity sensors, motion sensors, and light sensors.

• Temperature sensors - measure temperature changes

• Pressure sensors - measure pressure changes

• Proximity sensors - detect nearby objects without physical contact

• Motion sensors - detect movement or changes in position

• Light sensors - detect light intensity or brightness

Safety relay is an electromechanical device that monitors the safety functions of a machine and stops it if a safety issue is detected.

• Safety relays are used to monitor safety functions such as emergency stops, guard doors, light curtains, etc.

• They work by using input signals from safety devices to determine if the machine is in a safe state.

• If a safety issue is detected, the safety relay will open its contacts and sto...read more

Star-delta starters reduce inrush current and provide smooth motor starting for three-phase induction motors.

• Used for starting large three-phase induction motors.

• Reduces starting current to about one-third of direct-on-line starting.

• Involves two configurations: star (Y) and delta (Δ).

• Initially connects motor windings in star, then switches to delta after a set time.

• Example: A 50 HP motor may use a star-delta starter to...read more
