What is Moving Iron Instrument?

A moving-iron instrument is generally used to measure alternating voltages and currents. The moving element is an iron vane/plate. This iron is moved in a magnetic field produced by a stationary coil, which is excited by the current. On excitement, the coil behaves as an electromagnet, and the vane moves in such a way that the flux increases. Force is produced in the direction which results in the increment of coil inductance

How to Calculate Time Constant of Moving Iron Ammeter?

Time Constant of Moving Iron Ammeter calculator uses Time Constant=Shunt Inductance/Rsh to calculate the Time Constant, The Time Constant of Moving Iron Ammeter is the time required by the system to respond to change in shunt resistance or inductance. Time Constant and is denoted by τ symbol.
