Patent number: 10324140Abstract: Zero sequence current sensors for single-phase and multiphase power systems are disclosed. In one implementation, a zero sequence current sensor is positioned between conductors associated with a single-phase power system or a multiphase power system. The current sensor may be shaped to accommodate maintaining a substantially equal distance between the conductors associated with the single-phase power system or the multiphase power system.Type: GrantFiled: September 6, 2016Date of Patent: June 18, 2019Assignee: Littelfuse, Inc.Inventors: Daniel R. Gilman, Kip M. Larson, Brian Johnson

Patent number: 6534947Abstract: A method and apparatus for controlling an electric motor pump. The method includes the acts of providing an AC power signal having a positive half cycle and a negative half cycle, measuring the voltage of the AC power signal and generating a first two-state output signal that is in a logic high state when the measured voltage is on the positive half cycle and that is in a logic low state when the measured voltage is on the negative half cycle, and measuring the current of the AC power signal and generating a second two-state output signal that is in logic high state when the measured current is on the positive half cycle and that is in a logic low state when the measured current is on the negative half cycle.Type: GrantFiled: January 12, 2001Date of Patent: March 18, 2003Assignee: Sta-Rite Industries, Inc.Inventors: Steven A. Johnson, Kip M. Larson, Dee R. Walker
