NOVELTY - The transfer method involves generating alternating current (AC) power (103), and guiding, at least partially underwater, the AC power through a cable (111) from first end (113) of cable to second end (117) of cable. A first reactor (115) is connected near the first end of cable. A second reactor (119) is connected near the second end of cable. The inductances of reactors are selected to at least partially compensate for reactive power generated in the cable. The inductances of reactors are adjusted to avoid resonances close to the frequency of AC power.    USE - Transfer method for conveying electrical power in sea, in particular to subsea grid to provide electrical power at subsea exploration site.    ADVANTAGE - Provides AC consumers with AC power in simpler manner and requiring smaller or lighter equipment than existing system. Enables secure and reliable operation of transferring the electrical power in particular to subsea grid since resonances occurring within the cable depending on the frequency of AC power and the length of cable are reduced. The compensation for reactive power generated in the cable is made more effective, in particular in order to reduce change of the voltage when load changes regarding its power consumption by providing further reactors. The compensation of capacitor effect is improved since inductances of the reactors and/or further reactors are selected based on frequency of the AC power and properties of the cable, in particular the capacity of part or total of the cable the reactor is associated with and/or connected to. Improves compensation of the reactive power generated in the cable since some reactors are connected and other connectors are not connected to the cable depending on configuration in particular depending on power consumption of the load connected to second end of cable. Improves transfer of AC power since resonance peaks are reduced and resonances close to the frequency of AC power are reduced by appropriately adjusting or selecting the inductances of reactors and/or the further reactors. Improves security and reliability of the method while equipment is avoided to be damaged since extremely high voltage is avoided when frequency between resonance peaks of calculated voltage ratio curve is selected. The equipment required for performing the method is less voluminous and also lighter and potentially also less expensive than equipment which is required for performing DC transmission method since size of iron cores within respective transformers is reduced by providing power as AC power compared to situation in which electric power is transferred using DC transmission method-.
