US Patent:

20190265310, Aug 29, 2019

Filed:

Mar 4, 2019

Appl. No.:

16/291725

Inventors:

- Kent WA, US
Michael M. Van Schoiack - Bellevue WA, US
Roy Gilbert - Redmond WA, US

International Classification:

G01R 31/40
F16K 37/00

Abstract:

A system and method to detect the loss or disruption of one or more phases of a three phase alternating current (AC) power source used in the operation of a valve actuator. The loss of one or more phases of a three phase AC power source may cause a peak in AC power output. While a peak in AC power output may not affect an operation of electronic circuitry, all three phases are often required to safely operate other hardware components, such as an AC motor that is associated with the valve actuator. Therefore, in response to detecting the loss or disruption of at least one phase of a three phase AC power source, this disclosure presents a system and method to inhibit damaging operations such as operating an AC motor associated with a valve actuator, and continuing to operate communications and diagnostic circuitry to report the condition.
