METHOD OF MEASURING ELECTROMAGNET MOMENT OF THREE-PHASE ASYNC ENGINE

摘要

FIELD: measuring technique. ^ SUBSTANCE: method can be used for measuring electromagnet moment of submerged async engines used in oil and gas industry. Currents and voltages are measured in phases of circuit which feeds submerged engine. Length of cable connecting engine with circuit is measured additionally. Phase voltage losses are measured at inductance and ohmic resistances of wires of cable line. The values are summed with real values of like phase voltages of feeding circuit. Three-phase voltages and measured phase currents of feeding circuit are used during process of measurement of resulting vector of stator' magnetic flux linkage and resulting vector of stator's current. ^ EFFECT: widened functional abilities. ^ 3 dwg
