Positioning and Function: REF615 is an intelligent electronic device (IED) designed specifically for public substations and industrial power system feeders, used for the protection, control, measurement, and monitoring of radial, ring, and mesh distribution networks (including distributed generation). It is a Relion ® The members of the 615 protection and control series products adopt compact and withdrawable unit designs, fully leveraging the potential of the IEC 61850 standard for communication and interoperability between substation automation equipment.
Measurement and recording function
Measurement parameters: Continuously measure phase current, current symmetry component, and residual current. If voltage measurement is included, residual voltage, phase voltage, and voltage sequence component are also measured. According to the standard configuration, frequency measurement is also provided to calculate the current demand value within the user's selectable preset time frame, thermal overload of the protected object, and phase imbalance value based on the ratio of negative and positive sequence currents. Three phase power and energy measurement, including power factor, are provided.
