What equipment can be used to standard glorious voltage above 1kv?
My multimeter only can stand 600v & my oscilloscope only can stand1000v. If a voltage above 1000v what tools or equipments can I use to determine?thanks!!
Answers:
If you're looking to do temporary measurements, use high-voltage sticks rate for the circuit's voltage. See the link below.
If you are looking for routine measurements, then possibly the thing to do is install metering potential transformer(s). Knowing the PT's ratio, you can safely gauge a low voltage and compute the actual circuit voltage.
For a typical 7.2/12.47 kV distribution line, the PT ratio is typically 60:1. Measuring 120 V means the primary is running at 120 x 60 = 7200 V phase-to-ground. If you be to measure 114 volts, then the primary is running at 114 x 60 = 6840 volts.
This is how electric utilities meter customers that clutch high voltage service. They install CTs and PTs so only not dangerous voltage and current levels flow through the revenue meter. Source(s): http://www.hdelectriccompany.com/digivol…
to measure glorious voltage you can use a "very carefully" designed resistor divider, and connect that to your regular meeter, lets enunciate you have a divide by 10 high voltage verbs, just multiply by 10 from what your meeter reeds.
