FIELD: electricity.
SUBSTANCE: matching of three-wire power line with electrical load is reached in result of fulfilment of certain conditions involving comparison of actual and reference load resistance, voltage in the line end and currents supplied to the load. Initial data on voltage and current in the line can be obtained through interfaces or sensors made in a form of voltage or current transformers or in a form of voltage dividers and alternating-current shunts. In result of initial data processing the processor shapes control signals for correcting elements and devices for voltage regulating under load in line transformers or automated process systems can be used as such correcting elements.
EFFECT: reducing losses of electric energy, reducing distortions of voltage and current curves.
