Webmakes the determination of the open phase condition. When an open phase condition is detected, the relay then triggers an annunciation alarm for plant operations, as well as a process bus compliant digital fault recorder, which also receives its data via Ethernet link from the OCT electronics. Figure 1 – Open Phase Detection System using OCTs and WebPhase monitoring relays protect against equipment failure caused by faults in a 3-phase system, such as phase reversal, phase loss, phase unbalance, overvoltage and undervoltage. These relays are compatible with Wye or Delta systems and are available in a range of voltage inputs. Electro-Mechanical Relays Optocoupler Relays Solid State Relays
Web12 de out. de 2024 · Types of Relay Based on the polarity: Polarized relay: These are similar to the electromechanical relays but there exists both permanent magnet and electromagnet in it, the movement of the armature depends on the polarity of the input signal applied to the coil. Used in telegraphy applications. Non-polarized relay: WebEMD monitoring relays can be used to monitor overvoltage, undervoltage, overcurrent, undercurrent, phase failure, phase sequence, phase asymmetry, power factor, active power, motor winding temperature, and fill levels. The current relay detects and monitors sinusoidal alternating currents in the frequency range from 45 to 65 Hz. More information.
