Star delta contactors are used in electrical systems to control the starting and stopping of three-phase motors.
Star delta contactors are used to reduce the starting current of three-phase motors.
They are commonly used in industrial applications where large motors are used.
The contactors switch the motor windings from a star configuration to a delta configuration.
This reduces the voltage across each winding and limits ...
There are two main types of motors: AC motors and DC motors.
AC motors: synchronous and asynchronous
DC motors: brushed and brushless
Other types: stepper motors, servo motors, linear motors
Motors can also be classified by their power source, size, and application

The Loto system stands for Lockout/Tagout, a safety procedure used to ensure that dangerous machines are properly shut off and not started up again during maintenance or servicing.
Loto system involves locking the energy-isolating devices with individual lockout devices to prevent the machine from being turned on
Tagout involves placing a tag on the locked device to indicate that it should not be operated

I was interviewed in Jul 2022.
HVDC is a technology used to transmit high voltage DC power over long distances. Offshore connections refer to power transmission from offshore wind farms.
HVDC is more efficient than AC transmission over long distances
Offshore connections require specialized equipment and installation techniques
HVDC is used for offshore connections to transmit power from offshore wind farms to the mainland
Examples of HVDC projects incl...
