Abstract
A generator system includes a generator controller for monitoring the operation of generator cable. The generator controller is configured to receive a first signal indicative of a generator output and a first connection of a generator cable and a second signal indicative of a second connection of the generator cable. The generator controller is configured to calculate a characteristic value for the generator cable based on the first signal and the second signal and compare the characteristic value for the generator cable to a threshold value. A generator status message or a generator command is generated in response to the comparison. The characteristic value may be resistance of the generator cable.
Claims18
A method for monitoring a generator cable of a generator system including a prime mover and an alternator:
- receiving a first signal indicative of a generator output and a first connection of a generator cable connected to the alternator;
- receiving a second signal indicative of a second connection of the generator cable connected to a load supplied by the alternator;
- calculating a characteristic value for the generator cable based on the first signal and the second signal;
- receiving temperature data for the generator cable;
- calculating a threshold value from the temperature data and at least one generator cable property value;
- performing a comparison of the characteristic value for the generator cable to the threshold value calculated from the temperature data;
- and
- generating a generator command in response to the comparison.
An apparatus including a prime mover and an alternator comprising:
- a first electrical path for a first signal indicative of a generator output from the alternator and a first connection of a generator cable;
- a second electrical path for a second signal indicative of a second connection of the generator cable to a load supplied by the alternator;
- and
- a controller configured to calculate a characteristic value for the generator cable based on the first signal and the second signal, calculate a threshold value from temperature data and at least one generator cable property value, and perform a comparison of the characteristic value for the generator cable to the threshold value,
- wherein a generator status message or a generator command is provided in response to the comparison.
A generator comprising:
- a first breaker coupled to a first electrical path for a first signal indicative of a generator output and a first connection of a generator cable to an alternator of the generator;
- a second breaker coupled to a second electrical path for a second signal indicative of a second connection of the generator cable to a load powered by the alternator of the generator;
- and
- a controller configured to calculate a characteristic value for the generator cable based on the first signal and the second signal and perform a comparison of the characteristic value for the generator cable to a threshold value,
- wherein the controller is configured to modify the threshold value based on temperature data for the generator cable and at least one generator cable property value,
- wherein a generator status message or a generator command is provided in response to the comparison.
