My multimeter only can stand 600v & my oscilloscope only can stand1000v. If a voltage above 1000v what tools or equipments can I use to measure???thanks!!

If you're looking to do temporary measurements, use high-voltage sticks rated for the circuit's voltage. See the link below.
If you are looking for routine measurements, then perhaps the thing to do is install metering potential transformer(s). Knowing the PT's ratio, you can safely measure 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 were to measure 114 volts, then the primary is running at 114 x 60 = 6840 volts.
This is how electric utilities meter customers that take high voltage service. They install CTs and PTs so only safe voltage and current levels flow through the revenue meter.

The 13V. is a lot greater possibly to be a concern than cutting-edge (amperage) concerns. it may desire to be wonderful, even even with the shown fact that it relies upon on the particular application. maximum cutting-edge instruments will tolerate diverse voltages from adapters, as battery charging is controlled via inner circuitry interior the instruments (assuming a battery operated gadget here). A cutting-edge score is the optimal an adapter could be made to furnish. yet how lots is supplies you relies upon on what it is hooked as much as. The gadget will in basic terms draw the present it desires. possibly ok, yet be cautious it quite is the two DC or AC output to verify the unique, and if DC, that connector polarity is right.

to measure high voltage you can use a "very carefully" designed resistor divider, and connect that to your regular meeter, lets say you have a divide by 10 high voltage probe, just multiply by 10 from what your meeter reeds.
read this to show you how complex this topic really is.
