UM3™ LINE MONITOR FOR UNDERGROUND DISTRIBUTION CIRCUITS

Sentient UM3 line monitor

Sentient Energy’s UM3™ Line Monitor is the next addition to our growing suite of intelligent sensors that makes advanced grid analytics available for underground distribution circuits for the first time. Sentient’s UM3™ extends the capabilities of the MM3™ and ZM1™ line monitors to provide equivalent capabilities to underground circuits to detect, capture, analyze and communicate faults and non-fault disturbances. The UM3’s modular design allows utilities the ability to address their underground priorities such as padmounted switchgear or underground vaults, with one uniform solution.

MODULAR APPROACH Reduces complexity

Underground equipment complexity ranges from simple underground pad-mounted transformers to somewhat complex pad mounted switch cabinets to the very complex and challenging environments of underground vaults and manholes. Large numbers of cables in close proximity and often submerged, present significant obstacles in providing robust line monitoring solutions that communicate results over mesh and cellular networks. The Sentient UM3 is the first modular solution available to address these challenges in various configurations of underground equipment. Sentient’s UM3™ Fault Monitor app (cFCI®) uses advanced fault detection algorithms, capable of wirelessly communicating fault information immediately to the utility control center via SCADA/DMS or OMS. With cFCI®, operators can dispatch crews to the correct location based on an immediate alert notification.

COMMUNICATES OVER BOTH MESH AND CELLULAR NETWORKS

The UM3 is designed to communicate using either Advanced Metering Infrastructure (AMI) or Distribution Automation (DA) mesh networks and cellular providers.

ADVANCED LOAD MONITORING

Sentient Energy’s UM3 Log-I app continually measures current values and derives the most useful values and averages for load monitoring purposes. The Sentient Energy Log-I app gives the operator visibility into the network loading conditions, and enables maximizing asset utilization by basing asset replacement and network operational decisions on accurate, real data rather than best-guess simulations or state estimations.

HIGH-RESOLUTION WAVEFORM CAPABILITY

Equipped with high resolution waveform capability at a rate of 256 samples per cycle, Sentient’s UM3 captures and records fault and disturbance waveforms that occur on underground cables and equipment. Waveforms are used by Sentient’s Grid Analytics Applications and Disturbance Management applications to identify probable fault causes or identify failures before they cause future outages.
