Surge protection in modern watt-hour meter
Braking magnets in new watt-hour meter utilize Alnico V, high coercivity magnetic alloy having properties especially suited to this application; resistance to demagnetization by surge currents is attained by taking full advantage of high coercive force of Alnico V and by eddy current shielding of aluminum.
