ESM smart meter operates as a revenue meter (IEC 62052-11), a power quality analyzer (IEC 61000-4-30), and a measuring transducer.
As a revenue meter, ESM counts four-quadrant active and reactive energy. ESM uses its built-in memory to store power demands and energy readings by time-ofuse (TOU) tariffs.
ESM analyzes power quality in accordance with IEC 61000-4-30 standard (classes A, and S), and automatically generates power quality reports.
ESM measures the parameters of electrical grid, and can integrate with automation and billing systems.
ENMI display panel connected with a single patch cord can serve as a HMI for ESM. ENMI can be mounted separately, or attached to the back of ESM.
