Q1. What is star delta starter?
Ans. 
Star delta starter is a type of reduced voltage starter used in induction motors to reduce starting current.
• Consists of two contactors - one for star connection and one for delta connection

• Initially motor is started in star connection to reduce starting current

• After a set time, motor is switched to delta connection for full speed operation

• Used in applications where high starting current can damage equipment

Q3. What is eddy current formula?
Ans. 
The eddy current formula calculates the magnitude of induced currents in a conductor due to a changing magnetic field.
• The formula is given by: I = π * D * f * B * σ

• Where I is the eddy current (A)

• D is the diameter of the coil (m)

• f is the frequency of the magnetic field (Hz)

• B is the magnetic field strength (T)

• σ is the conductivity of the material (S/m)

Q4. What methods can be used to improve the power factor of a 130 kW load with a power factor of 0.7, and what rating of capacitor is required for this improvement?
Ans. 
To improve the power factor of a 130 kW load with a power factor of 0.7, capacitors can be used. The required rating of the capacitor depends on the desired power factor improvement.
• Install capacitors in parallel with the load to improve power factor

• Calculate the required capacitance using the formula: C = (P * tan(acos(pf))) / (V^2)

• Choose capacitors with the appropriate voltage and capacitance rating for the load

• Ensur...read more
