A method for operating a grinder pump station and inhibiting the likelihood of operation of a grinder pump assembly under at least one of a run dry condition and a blocked condition includes providing a wattmeter circuit operably connected to the grinder pump assembly and measuring real power using the wattmeter circuit during operation of the grinder pump assembly to process sewage received in a tank and discharge the processed sewage from the tank. The grinder pump assembly is automatically turned off based on the real power (e.g., average value of the product of instantaneous values of voltage and current over time) measured by the wattmeter circuit due to the at least one of a run dry condition and a blocked condition. |
