Hi, where can I find sample .dwg files of electrical plans of build, homes or commercial facilities. Regards.

If I have a power transformer without nameplate or any sign of its capacity, how can I determine an approximated capacity in kVA. Regards.

Thank you again for all your answers.

Thank you for your answers.

Thank you for your answer. This is going on in Dominican Republic. Our system and regulation is not as develop as yours and we have a lot of problem collecting the energy we send in our lines. About your suggestion Peebbe, I know that this problem is the client´s problem, but if we accept a...

Let me explain the problem. I work for a utility and we have two diffents fees for low voltage conection, depending on the power the consumer demand. If the costumer consumes more than 10 kW it receive the BTD fee, this means the consumer will reiceve a bill with charge for energy and power. If...

Does the NEC or NESC has some rule or standard about this service limiter?

The "EEUU" means United State and by market regulation I mean the laws that rules the distribution and trading of the electrical energy. Including the fees and how are they determine.

I am talking about load shedding. The unit doesn´t allow that the consumer exceed a setting of power (like 10 kW).

Where can I find information about the electrical market regulation and electrical fee in the EEUU. Thank you in advance.

I need technical information about power limiter for dwelling. Is there any standard or rule about what is consider a limiter and what not, and what are its specifications for dwelling. Thank you in advances.

Thank you all, in the end I can confirm that the accuracy is not affect if I1 (primay current) doesn't exceed the rating multiply by the RF.

I want to know if the accuracy of a CT ratio 20/5 is affected if the I1 (primary current) is 35 Amp and the RF (Thermal Rating Factor)is 2. The CT has metering purpose. Thanks in advance.

Where can I find information about the residential meter, old and new, of company like GE or Schlumberger. Thank you for your answers.

My point is that if the nominal voltage (net voltage)decreases and the power drew by the load is constant the current will increase. And some meters use this current, as the only parameter, to move a wheel (using the Eddy Current and the electromagnetic force) which is the motor of the clock...
