SYSTEM AND METHOD FOR MAINTAINING PROPER PHASE NEUTRAL WIRING IN A POWER SYSTEM

摘要

According to one aspect, embodiments of the invention provide a method of operating a UPS system, the method comprising receiving, at an input of a first UPS, input power from a power source, generating, with a first analysis circuit, a first signal indicative of a characteristic of the input power, receiving, at the analysis circuit, a second signal from a second analysis circuit of a device coupled to the power source, the second signal indicative of a characteristic of input power received at the second analysis circuit, analyzing with the analysis circuitry, the first signal and the second signal, determining, whether an improper wiring condition exists at the input, in response to a determination that an improper wiring condition does not exist, providing output power to an output of the first UPS, and in response to a determination that an improper wiring condition does exist, de-energizing the first UPS.

1. A method of operating a UPS system having a first UPS, the method comprising:
receiving, at an input of the first UPS, input power from a power source; generating, with a first analysis circuit within the first UPS, a first signal containing information indicative of a signal characteristic of the input power received by the first UPS; receiving, at the analysis circuit, a second signal from a second analysis circuit of a device coupled to the power source, the second signal containing information indicative of a signal characteristic of input power received at the second analysis circuit; analyzing, with the analysis circuitry, the first signal and the second signal; determining, in response to analyzing, whether an improper wiring condition exists at the input of the first UPS; in response to a determination that an improper wiring condition does not exist at the input, providing output power to an output of the first UPS; and in response to a determination that an improper wiring condition does exist at the input, de-energizing the first UPS.
