Webground on the C-phase transformer lead. − Existing relay protection schemes were not designed to detect this condition. − Both divisions of safety equipment were adversely impacted. − This event was significant because it revealed a design vulnerability where an open phase or open phase grounded condition would not be detected by the existing WebThis open condition de-energizes relay coil CR1, allowing relay contact CR1-1 to spring-return to its normal status (closed), thus sending power to the alarm lamp. From this analysis we see that the lamp fulfills the function of a high pressure alarm, energizing when the applied pressure exceeds the trip point.
