Good Information Allows for Good Decisions

Cyber Switching's Submetering Solutions

Submetering systems are designed to monitor and measure electrical power by various systems within a facility. Submeters can be easily installed to monitor HVAC, indoor and outdoor lighting, computer facilities, refrigeration, general receptacles, and electric vehicle charging stations. With advanced submeters in place, each system’s use of electrical power can be identfied and outlying heavy users can be targeted for energy efficiency programs.

Submeters are also designed to be installed to meter the electrical power use by subtenants in a commercial building, giving a facility manager the ability to track and bill-back for tenant power use. This allows for the recapturing of energy costs, and creates a cost-saving mindset in tenants as well.

Who Can Benefit from Submetering?

Armed with real-time information, a facility manager can take steps towards troubleshooting unexplained power use or implementing more effective energy cost saving initiatives. The key in all of this is that good information allows for good decisions and with power use that can mean an increase in a company’s bottom line as power “hogs” are identified and cost saving initiatives for power consumption are effectively implemented.

Why Should You Submeter?

Submetering provides facility managers real-time and historic data on power use and power quality on multiple subsystems in a building's infrastructure, including interior lighting circuits, exterior lighting circuits, HVAC systems, and any number of other isolated circuits. This can lead to a litany of benefits, including:

  • Reduced Energy Costs
  • Energy Use Planning for Time of Use Billing
  • Tenant Energy Use Billing
  • Cost Recovery/Allocation
  • Multi-Site Rate Negotiation with Your Utility
  • Performance Monitoring
  • Government Regulation Compliance
  • Power Integration with Building Management Systems

Introducing the CS-400 Submetering System from Cyber Switching Solutions

A Title 24 compliant smart submeter solution, the CS-400 provides all of the benefits of submetering and offers ease of installation and cost-effective performance for commercial building power metering and monitoring, in both new and retrofit applications. Cyber’s meters are one of the few meters UL Listed® for field installation into existing electrical subpanels.

Designed for performance at an unprecedented price point, the CS-400 solution provides capabilities and performance which, until now, have only been available in significantly more costly meters. The system is comprised of modular components to efficiently meet requirements in all applications.

The System Components

Building the System

The CS-400 system is based on a modular design. As noted previously, there are three primary components: the Submeter, the Hub, and the Gateway. The Submeters are UL Listed® so that they may be field installed into a new or existing electrical panel. The Submeters include 14-gauge sensing wires and can be connected to circuit breakers and CT-Coils in the panel. With the voltage sync capability, a minimum amount of wiring connections are needed. This reduces installation cost and complexity and increases system safety.

The Hubs are designed to be mounted outside the panels, with a connection to the Submeter module done with low voltage Cat5 or Cat6 cabling. This adds to the ease and safety of the installation.

The Gateways are also mounted outside the panels and connect to each Hub with standard Cat5 or Cat6 cabling. The Gateways are also connectd with standard Cat5 or Cat6 cabling to a standard network through which they can be accessed using any standards-based browser. That access provides the in-depth reporting and configuration used to managed the system. Optionally, Cyber's EMC software can be installed on an enterprise-level server for managing larger installations.

Scaling the System

The modular design of the CS-400 series makes scaling the system simple and cost effective. Each Submetering Hub supports up to eight individual Submeters, whether the meters are in a single large panel or in separate panels, as shown to the left.

Each Gateway supports and provides manageability to up to 7 hubs. This equates to up to 56 meters if the hubs are fully populated, as shown to the lower left. The Gateway then provides a management portal to give facility managers and system administrators the ability to monitor the power use of every Submeter connected through the Hubs to the Gateway.

To put this in perspecitve, to be Title 24 compliant a 50,000 square building could use as few as 3 meters to isolate and meter lighting, receptacles, and HVAC systems. Of course, a facility manager could elect to put in more meters to gather power usage of more systems, or to gather information by floor or department. The key here is both scalability and flexibility. Cyber's Submetering system fully supports both needs.

Voltage-Sync - A Unique Cost-Saver:  One of Cyber’s unique features is the use of voltage-syncing the submeters. This approach reduces the cost and complexity of installing submeters by as much as 87%. Only a single submeter needs to be connected to a metered panel to gather the panel’s voltage data. That base data is communicated through the Submeter Hub to the other meters in the system, reducing the material and labor that otherwise would be required to connect all of the meters to that panel. A true cost savings!
