What else can I help you with?
What is used to test permanent magnet generators?
you get it up to operating speed and see if it delivers full load voltage and current. if it has been severely overloaded the permanent magnet can be discharged causing the output to be low
How do you install capacitor bank?
It depends what it's for. If it's for power-factor improvement, then it is normally connected in parallel with the load.
Is it possible to synchronise two generators with no common electrical load to be exactly out of phase?
No, is it not permissible to synchronise two generators with no common electrical load to be exactly out of phase. Doing so would represent a double short circuit to both generators, and possible destruction of both generators. Whether it is possible or not depends on the design of the synchronizing circuit and/or the stupidity of the operator.
How much load can bear a 25kva transformer?
25 kV.A for a permanent load; more if the load is variable.
Is this normal during a parallel of two generators where lead generator is higher in both load ampere and reactive power than the lag generator but with the same frequency same kilowatt load?
No it is not normal. Ideally both the generators share the load equally provided both generator ratings and other parameters are same.

Describe the procedure for paralleling generators explain how load sharing is affected?
Paralleling generators involves connecting multiple generators to a common bus to share the electrical load. The procedure typically includes synchronizing the generators in terms of voltage, frequency, and phase before connecting them to the bus. Once synchronized, the generators can share the load based on their capabilities, with the load distribution influenced by their respective settings, such as governor control and droop settings. Proper load sharing is crucial to ensure that no single generator is overloaded, which can be managed through coordinated control systems that adjust output based on real-time load conditions.
Are Yamaha generators good quality?
Yamaha itself is a great brand and when it come to generators they have the best selections. These generators are heavy duty workers that can stand the load of heavy appliances.
Why droop ct used in generators?
Droop CT is used to control load sharing of the reactive power b/w paralleled generators.

What is meant by load in diesel generators?
Any device that uses the generator to supply its operating voltage is electrically classed as a generator load.
Does power load affect fuel consumption of portable generators?
Yes, the more load that is placed on the generator the more fuel it will use.
Why load shedding panels are used in substation?
If you have many Gas turbine Generators working on parallel, if any fault happened in one generator ( so this generator is no longer feeding the load ) load shedding panels will disconnect a group of predetermined Less important loads to help the working generators in the additional load (which may come after fault of the mentioned generator ).
Is this normal during a parallel of two generators where lead generator is higher in both load ampere and reactive power than the lag generator but with the same frequency same kilowatt load?
No it is not normal. Ideally both the generators share the load equally provided both generator ratings and other parameters are same.
How do you decide KVAR rating of capacitor bank?
Generally the capacitor rating of a bank are decided on the load factor.ie higher the KVAR higher the capacity.KVAR is the reactive power in which load angle differs with the load variation.If we know load factor multiply it by the sine angle which gives us the capacity of the cpapcity of the load bank.
