Motor Connections

Delta connection:
- Chosen for applications where high starting torque is crucial
- Commonly employed in industrial settings with heavy machinery or equipment with significant starting loads
Star connection:
- Chosen for applications where high starting torque is not a primary consideration
- Commonly used in situations where the mechanical simplicity of the star configuration is desired
- Often found in applications with moderate power requirements, such as fans, pumps

Motor Failures

Overheating:
- Caused by various factors, including overloading, poor ventilation, and block air flow
- Can damage insulation, bearing, and other components

History of SLPA

1918: Port of Colombo was administered by the Colombo Port Commission, a Government Department
1958: Port Cargo Corporation was set up to take over stevedoring and shore handling activities
1967: Port Tally and Protective Services Corporation was formed to perform on-board tallying and watchmen services
1979: Sri Lanka Ports Authority was constituted under the provisions of the Sri Lanka Ports Authority Act, merging the Colombo Port Commission Department and the two existing statutory corporations

Telephone Circuit

Dialing circuit: generates electrical signals that correspond to the digits dialed by the user on the telephone keypad
Bell circuit: generates the ringing sound that alerts the recipient of an incoming call

Workshop Tools and Equipment

Wire Wrapping and Unwrapping tool: used to wrap jumper wires on the MDF line side and unwrap jumper wires
Krone tool: used to connect lines to 10 pair krone

Electrical 1 Workshop

Ceiling fan motor winding: procedure for rewinding a table fan motor
Blower malfunction:
- Caused by mechanical damage, resulting in reduced airflow or no flow at all
- Solution: replace the blower fan
Blower motor malfunction:
- Caused by worn-out bearings, leading to noise, vibration, or complete motor failure
- Solution: replace the entire motor and check electrical connections of the motor

Refrigeration and Air Conditioning

Tools and Equipment:
- Manifold Gauge: provides readings of high and low side pressures
- Pipe Cutter: used to cut refrigerant pipes easily
- Pressure Gun: used to clean dirty parts of air conditioner by spraying a stream of water with high pressure
- Vacuum Pump: used to remove air and moisture from the refrigeration system
