LOW VOLTAGE HOT TO HOT TIMER

A computer-implemented method and system are provided to measure a time of a load transfer for an electrical system. A selection of a transfer mode is received, such as a closed or open transition transfer mode. Electrical signals from sensing leads or signals derived therefrom are monitored to sense a supply state of power from first and second power sources on the electrical system to a load. The sensing leads are connectable or couplable to the electrical system or a component thereof according to the transfer mode being implemented. An occurrence of a contact lift and an occurrence of a contact landing, which are associated with a load transfer operation, are identified from the monitored electrical signals or signals derived therefrom. A load transfer time is measured based on a timing of the identified occurrences of the contact lift and landing, and the selected transfer mode, and outputted.
