Historically, foamy urine is considered a warning sign for probable kidney disease. Nephrologists and urologists traditionally refer to it as a marker of proteinuria. Upon history and physical examination, many clinicians ask whether the patient has noticed foamy urine, and some even document a lack of it as a significant negative finding.
Phase synchronization. Phase synchronization is the process by which two or more cyclic signals tend to oscillate with a repeating sequence of relative phase angles. Phase synchronisation is usually applied to two waveforms of the same frequency with identical phase angles with each cycle. However it can be applied if there is an integer relationship of frequency, such that the cyclic signals share a repeating sequence of phase angles over consecutive cycles.
Phase monitor relays provide protection against premature equipment failure caused by voltage faults on 3-Phase sys-tems. All Prosense phase monitor relays are designed to be compatible with typical Wye or Delta systems. Phase monitor relays protect against single phasing regardless of any regen-erative voltages.n Wye systems, a connection to a neutral is not re-quired.The relay is energized and the LEDon when the sequence is correct. Any fault will de-energize the relay and turn off the LED. Re-energization is automatic upon correction of the fault condition.
