Disclosed herein are embodiments of systems and methods for determining the state of health of a generator battery set and its ability to supply generator starter motor with start-up energy by capturing a profile of voltage across terminals of the battery during a supply of electrical energy from the battery to the starter and comparing the captured voltage profile to a reference voltage profile to determine if a difference between the captured voltage profile and reference voltage profile exceeds an acceptable amount.

Multi-phase power meter configured for monitoring generator battery voltage

A power meter for measuring power parameters on one or more electrical power lines/loads is configured to include a revenue class metering module and a power quality metering module. The revenue class metering module and the power quality metering module may use the same measured voltage and current signals to generate revenue accurate power consumption information and power quality information, respectively. The power meter may also include a plurality of filters configured to attenuate high frequency signals included in the voltage and current signals. Each of the filters may be configured with a corner frequency, gain and signal propagation delay that is substantially equal. The filtered current and voltage signals may be received and processed by the revenue class metering module, and the power quality metering module to generate revenue accurate power consumption information and power quality information, respectively. Alternatively, the filtered current and voltage signals may be received and processed by the power quality metering module to generate power quality information, and unfiltered current and voltage signals may be received and processed by the revenue class metering module to generate revenue accurate power consumption information.

Revenue class power meter with frequency rejection

A sensor apparatus for measuring power parameters on a power conductor, such as a high voltage transmission line may include a corona structure, an electronics assembly and a conductor mountable device. The corona structure may define an outer boundary surrounding the electronics assembly and the conductor mountable device. The corona structure may shield the electronic assembly and conductor mountable device from a corona produceable with the power conductor. The conductor mountable device may be a power parameter measurement device, such as a current sensor assembly. The current sensor assembly may be a split-core design that includes multiple transformer cores. The electronics assembly and the conductor mountable device may powered from a line voltage suppliable on the power conductor. Data may be wirelessly transmitted and received with the sensor apparatus.
