Hi chuckey thanks so much for your feedback ,
I have some comments if u don't mind
1- Yes It's cheaper , but It would be more easy if the step-up transformer is Y-Y , then ground all neutrals.
4- I didn't see any rectifier in the homopolar generator , it looks exactly like a transformer. where...
Hello everybody
In a power plant using Fuel Generators, I came across some technical things that I couldnt undertand
Well its a 4x2000KVA (4 generators 2000 KVA) , these 4 generators connected with Busbar to step-up transformers (410 V -> 11kV) , after that from the step-up transformer to HV...
Hello everybody
I need some help to understand the role of some capacitor in an industrial drawing
I made a drawing of the electrical installation
I don't understand the circled part ?
Hello :)
I have a 6 months intership withing a steel factory , and I want to understand how the induction furnaces operates,
I have a question about the eddy current wich appear when putting a metal (or scrap) in a magnetic field.
well the eddy current is big enough to melt the scrap , but is it...
Hello :)
I have a dehumidifier Munters MH270 :
here is the nameplate :
What does these technical specifications means :
Reduced airflow
Available static pressure
Reactivation air
thank you in advance :)
i know how AC motor operates !
i don't want to monitor the motor current , i just need to know if the motor is on or not
the 220V that i'm talking about is not the Motor power supply , its the command circuit power supply , i want to monitor the voltage in the contactor (it's just like...
i need to see if a motor is working or not , i tough about using current sensor or relay (the best solutions) , i just can't find them here where i live
thats why i need a fet , its going to work like a switch allowing 5V to go to the µController when the motor is On.
hey everybody , is it possible to drive a FET with a sinusoidale voltage of 220V , and if possible i want it without using a rectifier
thank you in advance
Thank you so much for your help , well its works very fine right now using the mosfet , i didn't find the 74HCT4051 he only gives me 4051 (that what is writing in the shield) and i couldn't drive it with 2.7 directly , now it is driven with 5V using mosfet and works just fineThank you so much...
The load is a 4051 8 chanel analog multiplexer , the high level of the selector pins A,B and C is 5V , i can't use my µC (2.7 output) that's why i need to use a Transistor as a switch
