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

To use a third party device in a PLC, you need to establish communication protocols and configure the PLC to send and receive data from the device.

• Identify the communication protocol supported by the third party device (e.g. Modbus, Profibus)

• Configure the PLC to communicate with the third party device using the identified protocol

• Map the data points between the PLC and the third party device to ensure seamless data exc...read more

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)

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
