Distribution Cabinet Metering Module: Standard And Non-standard Engineering Logic

This depends on the monitoring needs, cost structure, and physical space constraints of the power distribution system. Metering functions are independent of the core power distribution tasks, exhibiting a high degree of modularity and optionality.

Metering systems are not a mandatory component of the Powbinet system. The core mission of the distribution cabinet is to safely distribute electrical energy, implement overload and short-circuit protection, and provide an operating interface. Metering is an additional monitoring and management function; the demand side decides whether to include it based on energy efficiency audits, cost allocation, or preventative maintenance objectives.

Integrated metering modules face both physical and electrical constraints. Current transformers (CTs) or Rogowski coils require specific installation spacing, and busbar perforation locations must be precisely pre-defined. High-precision energy metering chips (such as the ADE9000 series) are sensitive to switching noise and temperature drift; independent compartments or shielded designs are often necessary. Communication interface (RS485, Modbus) wiring paths must be determined concurrently during the cabinet planning phase.
