- Q4. WHAT IS THE 4 POLE MOTER RPM..
- Ans.
The RPM of a 4 pole motor is determined by the frequency of the power supply and the number of poles.
The RPM of a 4 pole motor is directly proportional to the frequency of the power supply.
The RPM of a 4 pole motor is inversely proportional to the number of poles.
For example, a 4 pole motor connected to a 60 Hz power supply will have an RPM of approximately 1800.
If the power supply frequency is increased to 120 Hz, the...
- Q5. CAN U CONVERT 10KW MOTER INTO HP

Therefore, 10 kW = 10 x 1.34 = 13.41 HP
Conversion formula: HP = kW x 1.34
- Q6. WHAT IS ISOLATER
- Ans.
An isolator is an electrical switch that isolates a part of the circuit from the rest for maintenance or safety purposes.
Isolators are used to disconnect a circuit from the power source.
They are often used in high voltage applications.
Isolators are different from circuit breakers or fuses, as they do not provide protection against overloads or short circuits.
They are commonly used in industrial settings and power distr...

- Q2. What is the best method in power transfers?
- Ans.
The best method in power transfers is through high voltage transmission lines.
High voltage transmission lines are more efficient in transferring power over long distances.
