hay everybody
Please any body help me how to design high current(0-2A)
and high voltage(0-1000V) measuring circuits to dispaly the
voltage & current on the digital dispaly.

Use a DC-DC converter to decrease the voltage. (Buck Convertor) Then measure it
 

Hi,

I think that it posibly be simplier.

Just use a voltaje divider, formed for 2 resistors.

PE: put a 1KOhm resistor an a 1 MOhm in serie, and if you measure the voltaje on the resistor of 1k, you will have 1% of the total voltaje.

Be carefoul whith the resistor power ratings.

I hope that it helps you.

Regards.
 

Your voltage and current are DC or AC?
 

Thanks for the reply

My application is I want make a digital display using micro controller for DC power supply to measure Current (0-2A) & voltage (0-1000v). Presently we are using analog displays (current & voltage meters) by using shunt resisters.
Please any body provide me analog circuits or related sites for above project.

pl. specify your problem clearly.
 

power supply

I have to measure the current and voltage when 1KV,2A power supply
connected to the load.
