Conclusions
An improved treble-winding phase meter type D578 frequency error due to ±10% frequency deviation from its nominal value of 50 Hz does not exceed ±0.45%.
The circuit of a treble-winding phase meter with an RLC correcting network can be taken as a basis for designing a single-phase high-precision 50±5 Hz phase meter with a frequency error which fully meets the requirements of the appropriate GOST.
