The inductronic electrodynamometer for the precise measurement of voltage, current, power, and energy

The inductronic¿ electrodynamometer has been perfected and retested in its final form, and complete information concerning its design and performance can be given at this time. An interim report1 has been presented covering much of this material, and this paper includes the prior material as well as additional new information. A complete wiring diagram is now included along with output response-time curves and a means of controlling the damping by an external network. Shielding from the effects of external magnetic fields has been improved along with more precise frequency compensation. The network used to obtain this compensation is included.
