ESM smart meter operates as a revenue meter (IEC 62052-11), power quality analyzer (IEC 61000-4-30), and a multifunctional measuring device.

As a revenue meter, ESM measures four‑quadrant active and reactive energy, and uses its built-in memory to store power demand and energy readings by time‑of‑use (TOU) tariffs.

As a power quality analyzer, ESM conforms to Classes A and S of IEC 61000‑4‑30:2008. ESM provides immediate data and automatically generated power quality reports.

As a multifunctional measuring device, ESM provides measurement data via standard communication protocols for integration with automation systems. ESM IEC 61850 (Edition 2.0) implementation is certified UCAiug Level A by DNV GL (KEMA).

Similar to ENIP-2, ESM can connect to external ENMV modules for digital input and output. ENMI display modules are used for visualization.

For connection to electromagnetic current and voltage transformers or directly.
