Laboratory Calibration Method of SF6 Density Relays
SF6 density relays are a kind of important components of SF6 electrical equipment,and regular calibration of SF6 density relay is a necessary measure to ensure safe and reliable operation of power equipment.With the implementa-tion of digital SF6 density relays,the existing calibration methods have become inadequate.In this paper,the laboratory calibration method of SF6 density relays is proposed,and the performance calibration of SF6 gas density relay is performed by establishing a high and low temperature calibration platform.The calibration platform is verified competent in calibra-tion of digital SF6 density relays and conventional mechanical SF6 density relays,and may be useful in digitalizing of SF6 density relays.
