FAQs (Frequently Asked Questions):
What are capacitive voltage dividers used for?
They are designed for high-voltage AC waveform and amplitude measurement in scientific, industrial, and power distribution systems.
What is the maximum voltage these dividers can handle?
Up to 500kV in insulating oil, with custom calibration available for air use.
Can these be used in air instead of insulating oil?
Yes, but the division ratio will change. Factory calibration for air (e.g., 5000:1 in air) is available for improved accuracy.
How do these dividers ensure safety during high-voltage measurement?
The outer conductor is isolated from the case, allowing controlled ground connections to prevent ground loops.
What is the accuracy of these voltage dividers?
The standard accuracy is ±5%, with temperature compensation of ±1% from 20°C to 80°C.
