Precision metering for bulk power transfer and energy settlement
Apex 540 is a next-generation high-accuracy grid metering solution built for critical power transfer points where measurement certainty, revenue protection, and operational intelligence are essential.
At bulk power transfer points, even small metering discrepancies can lead to major revenue implications, settlement disputes, and reduced confidence in energy accounting. As utilities manage increasingly interconnected grids with conventional generation, renewable inputs, and multiple exchange boundaries, they need a metering system that goes beyond basic energy recording.
Traditional meters often provide limited operational data, fragmented communication, and insufficient insight into supply quality, leaving utilities with delayed decisions, reduced visibility, and higher reconciliation efforts.
Apex 540 eliminates that uncertainty.
Engineered specifically for grid- and transmission-level applications, it delivers ultra-high-precision measurement, detailed load profiling, event recording, harmonic intelligence, power quality monitoring, and secure multi-system communication. It acts not only as a revenue meter, but as a reliable source of network truth across every high-value interchange point. Supports metering for availability-based tariffs (ABT) and open access systems.
With Apex 540, utilities gain stronger settlement confidence, better system observability, and a future-ready foundation for substation automation and advanced grid management.
Brings settlement-grade accuracy, real-time grid intelligence, and secure communication to the most critical points of the power network.
0.1S accuracy for energy measurement, dynamic CT / VT error compensation, and transformer / line loss adjustment support precise billing and settlement.
Large data storage, dual loggers, harmonic measurement, and detailed power quality monitoring provide greater visibility into energy flows and network conditions.
Multiple communication interfaces and support for DLMS, MODBUS, and IEC 61850 enable integration with substation automation, SCADA, and EMS systems.
High-level DLMS security with data encryption and authentication helps protect meter data during communication with connected systems.
Wide-range voltage, current, and auxiliary supply inputs, together with configurable meter constants and multiple communication options, support diverse installation requirements.
A field-replaceable battery keeps the meter display accessible during power outages, while hot-pluggable communication modules simplify communication maintenance.
Apex 540 belongs in the part of the electrical network where confidence in data is directly linked to confidence in revenue, compliance, and grid operation. Whether installed at transmission substations, generation evacuation points, renewable pooling stations, or inter-utility exchange boundaries, it serves as a trusted measurement backbone for energy reconciliation and network intelligence.
For utilities, it reduces settlement uncertainty, improves observability across transfer points, and builds a stronger digital foundation for automation-led grid operations. For generation and renewable operators, it delivers highly reliable import-export accounting with complete transparency of energy movement. For grid managers, it provides a clearer picture of power quality behaviour, disturbances, and network anomalies that conventional revenue meters simply do not capture.
Apex 540 is not just built to measure energy. It is built to establish confidence in every megawatt that moves through the grid.
