Amp21D Digital Ammeter for MV Network Monitoring Application Guide

This document describes a cost-effective solution using a digital ammeter (Amp21D) installed on switchboard front plates to monitor medium voltage (MV) network current, enabling users to identify unnecessary loads, rebalance overloaded lines, and reduce energy consumption. The solution offers enhanced readout accuracy, self-powered batteryless operation, and easy installation for both RM6 and SM6 switchgear, with no on-site configuration required.
