ELECTRICAL EQUIPMENT CONTROL AND MONITORING SYSTEM Russian patent published in 2022 - IPC G01R11/25 H02H7/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to protective devices, and can be used to protect power equipment in the event of emergency conditions. The system contains, connected in series by a data bus: wired current sensor module 1, voltage sensor module 2, analog signal sensor module 3, discrete signal sensor module 4, control unit 5, wireless communication module 6, wireless sensor modules 7. The current sensor module 1 is made with current measuring transformers in the form of toroidal coils with primary windings connected to a controlled load and with the output of secondary windings connected to the current sensor module 1 connected via a wired data bus to the control unit 5. The voltage sensor module 2 is made with the possibility of connecting directly to the load supply lines and with the possibility of measuring voltage up to 1500 V, DC and AC. The analog signal sensor module 3 is designed to measure various physical quantities, and the discrete signal sensor module 4 is designed to connect sensors with a discrete output and load control.

EFFECT: expansion of functionality with an increased degree of versatility of application and scalability, ease of modernization and increased operational reliability due to the modularity of the proposed solution.
