Abstract: Acrel multi channels energy meter can realize up to 12 three-phase or 36 single-phase direct access measurement or 12 three-phase measurement through current transformers, this series energy meters are favored by communities, schools, enterprises due to their high accuracy, centralized installation, centralized management and high installation flexibility. This article introduces the application of Acrel multi channels energy meters in a school in Hong Kong.
Keywords: Multi channels energy meter, School
1. Project Overview
Hong Kong customers need to measure three-phase voltage, current and other parameters ranging from 2 to 12 channels in the school. Acrel ADF400L series energy meters meet the user's application and conditions.
2.Introduction of Acrel Energy Management System
Acrel energy management system is widely used in schools, commercial buildings, office buildings, industrial and mining enterprises, road traffic projects, etc.
