Chilworth JCI 164 High Voltage Adapter

General Description
The JCI 146 is a voltmeter adapter component designed for integration into larger experimental systems.

When combined with our JCI 140, the system enables measurement of live conductors with voltages up to ±60 kV DC via direct connection, providing an accuracy of ±2% (nominal) with minimal loading effects on the device under test.

The high input impedance and low capacitance of the JCI 146 make it suitable for more accurate DC voltage measurements. Other conventional techniques for direct high voltage measurement (e.g., high voltage meters, capacitive and resistive divider networks, etc.) often yield inaccurate results due to loading effects caused by the test setup.

This device can be used for cross-checking the calibration and accuracy of high voltage sources by utilities, calibration laboratories, and cable manufacturers, to name just a few application areas.
