An Adjustable Length Voltage Divider for Highly Stressed Transmission Lines
Abstract
A voltage divider has been developed for use in high electric field regions of liquid dielectric transmission lines. The monitor consists of an electrolyte-filled resistive primary divider, connected to a 100/1 discrete resistor secondary divider. The length of the primary divider is adjustable from 10 to 30 cm to accommodate flush mounting of the end electrodes for a range of transmission line spacings. We have routinely used the divider in water at fields > 250 kV/cm. The monitor, including the secondary divider, has a less than 5 ns risetime, and has a division ratio of 4,000 to 15,000 to 1 over its adjustment range. For a fixed length, the division ratio is independent of electrolyte resistivity.
