Grid Automation

The On-Ramp RPMA Network is designed for wide-area machine-to-machine communication. Only the RPMA Network has the reach and capacity to provide coverage for a utility’s entire service area. With an unmatched radio link budget of 172 dB, the RPMA Network can even cover underground devices up to a mile away and supports up to 16,000 devices per each RPMA Network Access Point. No other M2M wireless technology has the reach and capacity of On-Ramp’s RPMA Network. With ultra-low power operation and multi-year battery life for endpoint devices, the RPMA Network has dramatically lower TCO and faster ROI than any competing wireless technology for Grid Automation.

On-Ramp Total View

With a single network that supports smart meters, grid automation, demand response, and all of your M2M devices, you get total visibility into your smart grid. On-Ramp’s web based Total View application manages and monitors all of these devices. Offered as a fully hosted managed service or as part of our managed appliance, the Total View application enables real-time monitoring and management including remote disconnect, demand read, load shedding, remote configuration as well as a breadth of alarms to ensure complete operational visibility. For AMI applications Total View supports billing integration via numerous industry standard formats including NISC as well as functional MDMS integration via MultiSpeak and IEC61968-9. The Total View also has a complete XML API for enterprise integration including Oracle’s Outage Management System and OSISoft’s PI Historian.

Grid Automation Powered by On-Ramp

Schweitzer Engineering Labs (SEL) WSO-11

The SEL WSO-11 consists of an overhead FCI hardware platform capable of fault detection, current measurement, and other load statistic gathering. The sensor is used to rapidly isolate outages, detect and fix phase imbalances, and improve capacity planning and predictive maintenance. Its 10-year battery life minimizes device maintenance, and once installed, devices reliably report anomalies as well as daily status checks. All alarm and status information is presented on the On-Ramp Total View dashboard.

Schweitzer Engineering Labs (SEL) 8301A

The SEL 8301A consists of an underground FCI hardware platform capable of fault detection current measurement and other load statistic gathering for twelve separate inputs. The device can accept three separate types of input sensors, such as an input current sensing device or power sensor. The device is used to measure load current, detect outages, sense faults, and detect fault direction.

GridSense TransformerIQ-P (TIQ-P)

The GridSense TIQ-P smart transformer monitoring device provides condition monitoring to improve predictive maintenance, and grid performance metrics and alarms useful for extending the life of a transformer (e.g., top and bottom oil temperature, ambient temperature, load current, voltage and PF monitoring). All alarm and status information is presented on the On-Ramp Total View dashboard.

On-Ramp Wireless DNP3 Bridge

The On-Ramp Wireless™ DNP3 Bridge enables secure two-way wireless communications for DNP3 applications. On-Ramp Wireless’ DNP3 Bridge provides ethernet and serial connectivity for end-point devices including capacitor bank controllers, voltage regulators, transformers, reclosers, and switches. Distribution Automation back-office applications, including SCADA systems, are supported via integration over DNP3 IP. Key features of the DNP3 Bridge include:

  • Secure two-way communications between automation devices and utility back-office systems including SCADA
  • Compliant to Industry standard DNP3 connectivity protocols
  • Supports industry standard physical interfaces such as RS232, RS422/485, and Ethernet
  • Low power requirement with large Voltage input range (10-56V)
  • Ruggedized aluminum chassis supporting robust installations
  • Flexible device and back-office configuration supporting a wide variety of distribution automation applications

DNP3 Bridges can be deployed independently or as part of a larger Smart Grid network installation for greater cost savings.

Fastest Return on Investment (ROI)

The On-Ramp RPMA Network offers industry-leading capacity and range, providing communications for all Distribution Automation (DA) devices in a utility’s territory at significantly reduced cost of network infrastructure. The simple star topology enables very accurate network planning, rapid and flexible deployment scheduling, and lower operations and maintenance costs than competing technologies. Leveraging experience from large deployed networks and a Department of Energy-funded grant on San Diego Gas & Electric’s and Southern California Edison’s distribution systems, On-Ramp Wireless is delivering cost-effective DA solutions with predictable results. Whether a utility customer decides to purchase the network and manage deployment themselves, or take advantage of On-Ramp Wireless’ fully managed network service, a utility’s DA solution can be live within weeks of project go-ahead. The lowest total cost of ownership combined with rapid realization of automation benefits accelerates customer ROI for the On-Ramp DA solution.

Breadth of Monitoring Options – The Grid Edge

The On-Ramp Wireless partner ecosystem continues to expand with industry leading grid edge applications and new devices Connected by On-Ramp are hitting the market each quarter. Starting with FCIs, Smart Transformer Monitoring, and DNP3 reporting for Cap Bank Controllers, Reclosers, etc., utilities and industry leading manufacturers are accelerating their integration with the On-Ramp RPMA Network. The On-Ramp Total View application provides the necessary tools for device management and complete network visibility. On-Ramp TotalView presents a consistent and aggregated view into grid operations, and includes standard interfaces for easy integration with established utility OMS, historian, and SCADA systems. Finally, the On-Ramp RPMA Network will support Grid Edge, Demand Response (DR), and Automated Metering Infrastructure (AMI) on the same network.

Connect Anywhere

There is no other wide-area M2M network that can reach above ground and below ground devices simultaneously. Proven in a joint project funded by the United States Department of Energy (DOE) and in partnership with multiple Southern California investor owned utilities, the On-Ramp RPMA Network has been proven to penetrate below ground from distances up to a mile. The On-Ramp RPMA Network reliably covers back country and remote locations where cellular is non-existent or unreliable, as well as dense urban environments where RF noise poses interference challenges for most wireless technologies. In addition to consistently providing this industry-leading coverage, On-Ramp Wireless network planning techniques produce highly accurate network predictions, especially important when planning capital requirements for such difficult terrain and environmental challenges. Only the On-Ramp RPMA Network can cover thousands of devices anywhere.

Longest Battery Life

The On-Ramp RPMA Network can run entirely on batteries — the devices as well as network infrastructure. Designed for low bitrate applications, On-Ramp enables unmatched endpoint battery life; devices without access to line power can operate for up to 20 years, and powered grid devices with backup batteries continue to perform in the event of a catastrophic power outage event. On-Ramp Wireless field infrastructure can be deployed with primary or backup solar/battery systems, further extending the range utilities can monitor their critical assets.
