Even we asked from the maunufacture, until now, i dont know the accpetable range of resistance for fully charged condition.
e.g
25% or 30 % range of average resistance???
Is there anyone can share the information about acceptable internal resistance value for fully charged battery condition?
My battery specification is sunlight 12V 200Ah and charger setting is 2.23 V/cell.
Datasheet for battery manufacture states that 3.5 mΩ.
Within how many percentage is...
thanks for your advice.
I still want to know about that electri field is in the horizontal plane or vertical plance?
is the electric or magnetic field can penetrate the 5mm or 100 mm thickness partation wall(not plastic) and effect the electonic circuit at the other side in my case?
please...
For two 20kVA isolation transformer, when they are installed in very closed distance about 150 mm gap, is it possible any induce voltage effect to electronic circuit nearby?
Can it be possible the two transformer induction flux become a significant noise source to other electronic controller...
Hi I m facing with the main controller unit of industrial UPS that giving worng signal and detect same warning to UPS(total 5 unit).
UPS envirnment is oil rig.
Input is coming from gen set 690 ph ph 60 hz source.
Power analyzer proved input is no problem.
But input is delta 3 wires + ground...
How Can we know and decide to replace MCCB for what kind of overheating condition?
What is the acceptable temperature (refer to I.R reading data ) for MCCB?
<In 3 poles MCCB , 63 Amp ABB brand using with 16 mmsq cables>
In my case, one of the Phase contact got Hot Spot due to the cable cap...
1.Does anybody know about the effect on lifetime and MCCB functioning due to the overheat occured at one phase in 3 poles 63A ABB brand MCCB?
2.How Can we know and decide to replace MCCB for what kind of overheating condition?
3.What is the acceptable temperature (refer to I.R reading data )...
for me, i choose 8051 microcontroller to study.
According to my guide line person, he teached me,
1 basic digital couse (including combinational and sequential logic and state machine design ending with basic of PROM to PLD.)
2.8085 course including progrmming model achitecture and intefacing...
need help for power?
In our country, there is some problem in one of our power stations(Hydropower generator).
This problem is concerned with the following facts.
I would like to know about
1.the application of back to back connection of selenium finned rectifier in output of Hydropower...
Please answer my misunderstanding.Thanks a lot everyone for solving.
1.Can overcurrent in the secondary(load) cause primary loading current?
2.Does Overload in the primary mean current due to output<Load> or other facts?
3.Why two current sensings is used in this circuit (overcurrent and...
In SMPS design of attachment file,
I found that Overvoltage and Overcurrent are sensed from secondary of Flyback trasformer.Overload current sensing is from primary.I would like to know some questions about the circuit like this above.
1.Can current and voltage sensing circuit be connected to...
The driver i know is the intermediate amplifier(not a final state),that drives other state .
For the input that final amp can't handle ,it is used.
It drive other active devices rather than passive.
