Frequency Meters Now-a-days electrical energy is exclusively generated, transmitted and distributed in the form of alternating current. It is very important that frequency in power networks is maintained strictly constant as any change in frequency may affect the operation of a number of automatic control devices. Many *different systems are in common use for the measurement of frequency. However,in power system, frequency is generally measured by an instrument called frequency meter. A frequency meter is a direct reading instrument and is used where frequency variations are in close limits e.g. in a power system. There are a number of different types of frequency meters but the most commonly used ones are
