Our range of CVR's are non inductive shunts designed to operate over a wide bandwidth, ideal for testing switching rise times for both AC and DC power systems, especially where phase angle is a consideration in power calibration systems. Very useful for adding or extending the current range of Frequency Response Analyzers and Multimeters. CVR's can be used with phase angle meters, where phase angle between voltage-voltage, voltage-current or current-current is required, ideal for phase protection, power meters, wattmeters, energy meters and current transformer calibration.
