 Products

  • Phase ID 6000
    PSI’s Phase ID System correctly identifies the phase of any energized conductor in about one second. Perform Phase Identification Measurements in manholes, in vaults, and in aerial work....

  • PSI’s novel Phase ID System is a non-intrusive tool that is versatile and easy to use. The system correctly identifies the phase of both low and medium voltage overhead distribution cables including MV Spacer cable.

    The PSI Phase Identification System accurately identifies the phase of pad mounted equipment with both live and dead front connections.  In addition, the PSI Phase ID system determines the various phases of a pad mounted transformer on both the low voltage and medium voltage cables.  The Phase ID 6000 has these features:​

    • Design for both OH & UG electric distribution systems
    • LCD displays phase and phase angle in one (~1) second
    • Compensation for +/- 30 degrees from ΔY and YΔ connections
    • Dynamic range from 10V to 345 KV AC
    • Wireless remote display

    Phase ID 6000 tools provide accurate phase identification at any location. No recalibration is ever required, even when phasing circuits fed from different substations. 

    PSI’s Phase ID System offers fast, accurate and affordable phase identification.  The PSI Phase ID system enables utilities to improve the quality of operating practices and their readiness to deal with emergencies. The potential benefits are significant and result in:

    • Improved decision-making process during system emergency conditions
    • Improved overall distribution system reliability
    • Reduce operating and maintenance costs
    • Enable Smart Grid initiatives with accurate phase data.
  • CEMesh
    CEMesh provides excellent visibility into the network cabling beyond the vault. This could enable your condition-based maintenance to improve planning and performance....

  • Introducing Secondary Network Monitoring

    Power Systems Integrity, Inc. (PSI) developed an advanced Secondary Network Monitoring System that is easy to install.

    No communication wiring is required!  CEMesh® uses the power delivery system as the communications wiring.

    PSI’s two way communication system is a generalized communication backbone for use in a low voltage secondary network.

    CEMesh®
    CEMesh® is the low cost and scalable two-way communications LAN between PSI Meshed Network Sensors (MNS) and the PSI CEMesh® to IP gateway that can back-haul virtually any measured parameter.CEMesh®
    The underground (LAN) portion of the communications is a Meshed Network power line carrier (PLC) communication system called CEMesh®. The PSI hardware that embodies this system consists of a Gateway and Remote Monitoring Units for use in virtually any underground sensing application.CEMesh®

    Individual MNS nodes participate as routers for other nodes. This makes CEMesh® less expensive to implement and operate than conventional PLC networks involving radial branches and centralized collectors.

    CEMesh® will provide a technical and economic advantage over other technologies for utility automation applications like meter reading. 

    Applications

    PSI’s Network Monitor senses Voltage, Current, Temperature, and Calculates Phase Angle, and PF. The system also accepts inputs from other IED’s and sensors, such as Manhole gases like H2 and CH4.

    Benefits

    Secondary Network Monitoring improves visibility of the Network providing a tool for condition-based maintenance that will lead to improved network planning and performance. Combined, these benefits have an impact on:

    • Improved system reliability and availability
    • Optimizing manpower and asset utilization
    • Improving public safety
    • Improved fault detection, location, and restoration of service
    • Reduced collateral damage due to cable burnouts
    • Online peak load monitoring
    • AMR backhaul through PSI’s fixed network
