Soft starters are preferred over star-delta starters for motor start and run due to their ability to reduce inrush current and provide smoother acceleration.
Soft starters provide a gradual increase in voltage to the motor, reducing inrush current and mechanical stress on the motor.
Star-delta starters provide a sudden increase in voltage, resulting in high inrush current and mechanical stress on the motor.
Soft starters ...
Encoders used in industrial include absolute, incremental, linear, rotary, magnetic, and optical encoders.
Absolute encoders provide a unique code for each position
Incremental encoders provide a pulse output for each position change
Linear encoders measure linear motion
Rotary encoders measure rotational motion
Magnetic encoders use a magnetic field to detect position
Optical encoders use light to detect position
VFD parameters are settings that control the operation of a variable frequency drive.
VFD parameters include frequency, voltage, current, acceleration/deceleration time, and motor overload protection
Frequency parameter determines the speed of the motor
Voltage parameter determines the amount of voltage supplied to the motor
Current parameter determines the amount of current supplied to the motor
Acceleration/deceleration t...

Ohm's Law is a fundamental principle in electrical engineering that relates the current flowing through a conductor to the voltage across it and the resistance of the conductor.
Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across it and inversely proportional to the resistance (R) of the conductor.
The formula for Ohm's Law is: V = I * R, where V is the vol...
The current unit is the ampere (A), which measures the flow of electric charge.
The ampere is named after the French physicist André-Marie Ampère.
Current is the rate at which electric charge flows through a conductor.
Other common units for current include milliamperes (mA) and microamperes (μA).
The voltage unit is measured in volts (V).
The voltage unit is denoted by the symbol V.
Voltage is the potential difference between two points in an electrical circuit.
Common examples of voltage units include millivolts (mV), kilovolts (kV), and megavolts (MV).

I applied via Campus Placement and was interviewed in Aug 2023. There were 2 interview rounds.
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...
