Abstract
Systems and methods are provided for a three-phase compensation system, whereby an electric circuit is configured to be connected with three input phases of a power source and to supply three respective output phases, said electric circuit further configured to compensate for one or two malfunctioning input phases of said three input phases by supplying current from a functioning input phase of said three input phases to replace a malfunctioning input phase.
Claims11
A three-phase compensation system, comprising:
- an electric circuit configured to receive three input phases of a three phase power source from which to supply three respective output phases, said electric circuit further configured to compensate for one or two malfunctioning input phases of said three input phases by supplying current from at least one of functioning input phase of said three input phases to compensate for the one or two malfunctioning input phases, wherein said electric circuit comprises first, second and third control relays connected with each other, each comprising first and second normally open in-contacts, first and second normally open out-contacts, first and second normally close in-contacts, first and second normally close out-contacts, a control in-contact and a control out-contact.
A method of compensating for a lost phase of a three phase-power source, comprising providing a three-phase compensation system, comprising:
- an electric circuit comprising first, second and third control relays connected with each other, configured to receive three phases of the three-phase power source, one to each of said first, second and third control relays respectively, and to compensate for a a malfunctioning of one of said three phases that does not supply current to its respective control relay, by supplying current to the respective control relay from one of the other two control relays.
A method of compensating for a lost phase of a three-phase power source, comprising:
- providing a three-phase compensation system, comprising:
- an electric circuit comprising first, second and third control relays connected with each other;
- said electric circuit configured to receive three phases of the three-phase power source, one to each of said first, second and third control relays respectively, and to compensate for a malfunctioning of two of said three phases that do not supply current to their respective control relays, by supplying current to the two respective control relays from the remaining control relay.
