FIELD: electricity.
SUBSTANCE: group of inventions relates to the field of measurement equipment, in particular to the systems of electric power measurement in electric circuits. The system of electric power measurement, the transformer point containing such system, and the method for measuring the electric power using such a system are disclosed. The system (20) is configured to measure the electric power of the current flowing in at least one secondary electrical conductor (42A, 44A, 46A, …, 42N, 44N, 46N) connected to the primary electrical conductor (34, 36, 38), wherein the primary conductor (34, 36, 38) and secondary conductor (42A, …, 46N) have actually the same voltage. This measurement system comprises the primary module (60) comprising the radioelectric transmitter (70) and the unit (66) measuring the voltage of the primary conductor (34, 36, 38), at least one secondary module (62A, …, 62N), comprising the radioelectric receiver (80A, …, 80N), the amperage sensor (76A, …, 76N) of the current flowing in the appropriate secondary conductor (42A, …, 46N), and a unit (126A, …, 126N) for calculating the electric power of said current in the secondary conductor. The primary module (60) comprises the first means (104) of compressing the measured voltage value (V1, V2, V3), and the means (106) of transmission in the direction of each secondary module (62A, …, 62N), the message (M1) comprising the contracted value of the measured voltage. The measurement system (20) comprises the means (106, 120A, 120N, 122A, …, 122N) of timing of each amperage sensor (76A, …, 76N) current with respect to epy block (66) measuring the voltage. The calculation unit (126A, …, 126N) is associated with the radioelectric receiver (80A, …, 80N) and is configured toensure the possibility of calculating electric power based on the voltage value received from the primary module (60), and the value of the current amperage measured.
