hi all,
do power houses store electricity when it is receive from the power plants (nuclear/thermal/solar/wind)? if yes how it is stored ? do they use batteries to store ?
or it is just a live transmission straight from the power plants to power houses and at last in our homes?
thanks...
need more clarification.
>>>>how we designate phase and neutral statically when it keeps on changing ?
you can easily establish the identity of neutral and phase without a problem.
>>> how can we establish the identity of phase and neutral when ground comes into picture?
is static...
hi all,
I have a basic question in electricity.
when there is no polarity in Alternating current then what is the idea of designating phase and neutral wires in AC?
as i know from sine curve AC runs bidirectional from phase side to neutral and then back.
thanks
i understand there are two transformers here.
1) current sensing transformer : CT sensor . I am not taking about this.
2) power adapter transformer : this is what i am talking about. it can be 9-0-9 (9V rms output value as per the doc as only 5v can be tolerated by Arduino) . what should...
now i understand, i can use any transformer of 6-0-6 or 9-0-9 or 12-0-12 rating. what should be the current rating in the transformer? i know in primary winding I will have 100 amp flowing...what about in secondary winding ? so that it should be safe for me as well as my Arduino.

hi all,
I am going to build energy meter using Arduino with the help given in below link.
but I do not find any AC to AC (230 to 9v) adapter in my country. what could be alternative
to this? any circuit DIY circuit to make it my self...
can i use TRIAC as in below link. will it be better than using relay and mosfet?
what is the pros and cons using TRIAC?

hi,
does this type of ldr and relay based light solution really saves money?
for saving energy consumed by my 6 watt LED street bulb, am I not losing power to run 5V relay module?

can we some how increase the voltage from 3V3 pin to 5v and use this powering up relay?
i see somewhere about logic sifter (3.3v -> 5v). it seems this is being used to step up voltage for sensor signalling purpose.
can this be also used to powering up relay?
some online seller do not give...
hi all,
i want to power up 5V 2-channel relay module with 3v3 pin of nodeMCU. Can it be directly connected or do i need some thing to step up voltage?
nodemcu is powered with 5v micro-usb cell charger. i do not want another/dedicated power source for relay module...
in this case how about dropping the modbus communication at all? i can connect all nearby sensors to a central Arduino for each room. and all these Arduino should connected over 2.4 ghz wireless link to a central Arduino. how do you see this design? will it fit to my requirement by seeing no of...
