CHAPTER 1 ─ INTRODUCTION

1.1 About the ElNet Meter Large consumers of electricity e.g. factories, hotels, hospitals, municipalities, need to know the history of their consumption and the quality of the power supply. Details such as Voltage, Current, Power Factor, Hertz, Neutral Current, Energy Demands and all electricity related events are recorded in the ElNet Energy & Powermeter. An additional feature of the Meter is the ability to measure Harmonics. Part of the Electricity Supply Authority’s bill reflects poor or good Harmonics in the consumer’s system, therefore it is in his interest to monitor Harmonics and try to improve it. These are all recorded on a continual basis and can be recalled and shown on the front panel display of the instrument with a few simple key-strokes any time the user wishes. The ElNet Energy & Powermeter is a compact, multi functional, three-phase Meter simple to install and is especially designed to integrate into Building Management Systems. It requires no special mounting and is ideally suited for mounting on the front face of any standard electrical panel. The Configuration and Setup is menu driven, with password protection. Communication with external devices is simple and is based on standard known technology. The ElNet Energy & Powermeter boasts a new innovative built in “Flash Memory”, which pioneers a new frontier into electrical measurement. It has a 1 MB of FLASH MEMORY with a capacity of recording up to 2 years of power malfunctions and interruptions.
