Mutual and self inductors compensated for change of frequency
Albert Campbell · Proceedings of the Physical Society · 1939
The effects of self and mutual capacitance on the electrical constants of mutual and self inductors can be compensated by various devices. For mutual inductors the usual system is a closed tertiary circuit coupled to both primary and secondary coils; the complete case of this is discussed mathematically and it is also shown that a similar arrangement (of closed secondary circuit) is effective for self inductors. A simpler system for these consists of a non-inductive shunt across the terminals, but the closed secondary is usually preferable. Several experimental examples are given.
