Bulk energy measurement, draw out type, long range site configurable with multi comms options

Apex 100 is an advanced high-end precision meter, specifically designed for generation, transmission and consumer bulk power transfer points. It supports the ICS DLMS open data exchange protocol for ease of reading and for integration with other systems. Comprehensive connectivity to back-end systems for monitoring and billing is provided via various communication technologies.

Application

  • Bulk energy transfer measurement and reconciliation
  • Captive power plants (CPP), feeder monitoring, grid substations and wind turbines
  • On-line monitoring of energy exchange at various interface points
  • Metering for availability based tariffs (ABT) and open access systems
  • Energy accounting systems

Benefits

  • Elimination of data gaps and revenue losses through use of hot-swappable meter modules, with automatic shorting of external current transformers
  • Minimal integration costs through multiple communications interfaces
  • Complies with the DLMS open data exchange protocol
  • Maximum revenue integrity through highest possible level of metering system accuracy
  • Efficient network management through accurate and detailed energy flow data
  • Suitable for diverse applications through wide-range voltage, current and auxiliary supply inputs

Features

  • Full four-quadrant import/export metering with active, reactive and apparent measurement
  • Total harmonic distortion (THD) measurement for currents and voltages
  • Draw-out type meter module with automatic CT shorting
  • Wide-range dual auxiliary power supply (AC and DC), with option for self-powering
  • Dynamic error compensation for external current and voltage transformers
  • Intuitive graphical display for parameters and data
  • Two metrology LEDs for simultaneous accuracy testing of different parameters
  • Four LEDs for energy redirection and status indication
  • Comprehensive data storage for current and historical readings and load survey data
  • Flexible time-of-day tariff and maximum demand support, with automatic billing
  • Multiple communication ports for local and remote data transfer and for interfacing with external systems
  • Interoperable DLMS and Modbus protocols for meter reading
  • Best suitable for Interface Energy Meters with 5 minutes Integration period (field configurable)
