What else can I help you with?
For a 18mw generation at 11kv what shall be mva rating of the 1133kv generator transformer?
I think, you are talking about a 11/33KV Transformer and by mistyping same has become 1133KV. However, rating shall be on the basis of 18MW +Loading factor . A 25/31.5MVA rating shall take care of of all these.
What is the form factor of a ATX power supply?
ATX is the form factor.
What is the impact factor of IJCSIT?
having No impact factor as per ISI web of knowledge
Which is the single factor which can make oe break a security plan?
A single factor that can make or break a security plan are people.
What is the key factor in computer performance and functionality?
The key factor in computer performance and functionality is the processing power of the central processing unit (CPU).
Why bridge rectifier is prefer over center type rectifier for low voltage applications?
there is no need of bulky centre tap in a bridge rectifier. TUF(transformer utilisation factor) is considerably high. output is not grounded. diodes of a bridge rectifier are readily available in market. *the PIV(peak inverse voltage) for diodes in a bridge rectifier are only halfof that for a centre tapped full wave rectifier,which is of great advantage.
What are common efficiencies for transformers?
Transformer utilization factor is the ration of power delivered to the load and ac rating of the transformer secondary.
What is the use of transformer utilisation factor?
It tells us how much is the transformer utilised in a given process. For a rectifier,TUF =(D.c.power delivered to the load)/(power rating of transformer secondary)
Why do bridge rectifier has higher rms value?
Bridge rectifiers have higher rms values because the ripple factor low.
How much is the transformer utilisation factor for half wave rectifier?
0.287. I hope this is an academic question and not something you're thinking of using in a circuit; three more diodes are cheaper than the kind of filter you'll need to clean up the output of a half-wave rectifier - AND you throw away half the voltage the transformer is putting out!
What is ripple factor of the Full-wave rectifier?
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
What is a peak load voltage out of a bridge rectifier for a secondary voltage of 15 Vrms?
A: Peak voltage is RMS multiplied by a factor of 1.41
What is the meaning of plant utilization factor in hydro power plants?
Utilization factor is a metric for power plants that describes how close the plant is operating to full capacity. For hydropower, utilization factor can be affected by droughts and seasonal variations in rainfall.
What is the need of form factor in transformer?
transformer is a static device hence it needs form factor.
What are the Advantages and disadvantages of half wave rectifier and full wave rectifier in terms of signals?
Advantages: Simple circuit and low cost.(ii)Disadvantages:1. The output current in the load contains, in addition to dc component, ac components of basic frequency equal to that of the input voltage frequency. Ripple factor is high and an elaborate filtering is, therefore, required to give steady dc output.(iii)2.The power output and, therefore, rectification efficiency is quite low. This is due to the fact that power is delivered only half the time.(iv)3.Transformer utilization factor is low.(v)4.DC saturation of transformer core resulting in magnetizing current and hysteresis losses and generation of harmonics.The type of supply available from a half-wave rectifier is not satisfactory for general power supply.This type of supply can be satisfactory for some particular purposes such as battery charging.
Why transformer power factor taken unity?
It isn't! A transformer operating at no load has a very low power factor.
What is utilization factor?
Ulitization factor is how much of the designed total is used. My house is fed off a 50KVA transformer. It's capable of supplying 50KVA continuously, but it's probably only gets used at its' full potential every once in awhile (when my neighbors and I wake up in the morning, and when we get home from work and eat dinner, perhaps). Say it only gets used at 30KVA on average. The utilization factor would be 30/50, or 60%.
