ZM1™ ZERO AMPERAGE GRID MONITOR

The Sentient ZM1™ is the world’s first advanced line monitor that can be deployed on distribution lines even where no or very-low amperage is available to power monitoring devices, including laterals, feeder tie points and rural distribution circuits. These line sensors allow utilities to expand fault detection, disturbance oscillography and intelligent analytics to the entire distribution grid, resulting in increased safety and significant improvements in System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI).

COMMUNICATES OVER BOTH MESH AND CELLULAR NETWORKS

The ZM1 communicates via either3G/4G cellular networks, Silver Spring Networks or Landis+Gyr mesh communications. No additional pole mounted equipment is required to connect with the line monitors.

EXCELLENT COMPLEMENT TO SINGLE PHASE RECLOSURES

The Sentient ZM1 is an excellent complement to single-phase reclosers, assessing their effectiveness and identifying the reclosure cause. The ZM1 records and communicates both the event leading to the reclosure and the operation itself, closing the information gap presented by today’s non-communicating reclosures.

MAINTENANCE-FREE OPERATION

The ZM1 operates completely maintenance free for 10 years or more on batteries, which are field replaceable for continued use of the ZM1 for many more years, and can be dispositioned via standard recycling.
