Why automate metering
Automated Meter Reading (AMR) systems are mandatory for new residential buildings and industrial facilities. Pulse-output meters are the most accessible integration method.
Connection diagram
A pulse-output meter connects to a data concentrator (DCU). The pulse output is a dry contact or optocoupler closing N times per kWh. Standard values: 100, 500, 1000, 5000 imp/kWh.
CT selection
For loads above 100 A, current transformers (CTs) are used. Accuracy class for revenue metering: 0.5S or 0.2S. Secondary rating: 5 A (standard) or 1 A (for long runs).
GorkyCAD and AMR
GorkyCAD automatically adds meters and CTs to the single-line diagram when the "Revenue Metering" option is enabled. The BOM includes all metering node equipment.
