Why power factor improvement plant is required?
Why power factor improvement plant is required?
Improving the PF can maximize current-carrying capacity, improve voltage to equipment, reduce power losses, and lower electric bills. The simplest way to improve power factor is to add PF correction capacitors to the electrical system.
What are the conditions for parallel operation of alternator?
The phase sequence of the busbar voltages and the incoming machine voltage must be same. The busbar voltages and the incoming machine terminal voltage must be in phase. The terminal voltage of the incoming machine and the alternator which is to be connected in parallel or with the Busbar voltage should be equal.
What is MVA rating of generator?
The capacity of a synchronous generator is equal to the product of the voltage per phase, the current per phase, and the number of phases. It is normally stated in megavolt-amperes (MVA) for large generators or kilovolt-amperes (kVA) for small generators.
Can also avoid penalty due to low power factor?
Consumers can avoid power factor penalties by installing devices for power factor correction, Install capacitors in the distribution system. While capacitor banks improve the overall system’s power factor, the individual machines which caused a drop in power factor would still remain the same.
What happens if power factor is low?
A lower power factor causes a higher current flow for a given load. As the line current increases, the voltage drop in the conductor increases, resulting in a lower voltage at the equipment. With an improved power factor, the voltage drop in the conductor is reduced, improving the voltage at the equipment.
Can you connect two transformers in parallel?
It is possible to connect transformers that have different polarities in parallel. You need to remember that you match up the polarities. The supply line polarity determines the primary polarity of the transformer. The primary polarity determines the secondary polarity of the transformer.
