Preface
One can only appreciate the magnitude of effort required to develop a dictionary by actually experiencing it. Although I had written nine other books, I certainly did not know what I was getting into when in January of 1996 I agreed to serve as Editor-in- Chief for this project. Now, after 2 1/2 years I understand. Unlike other books that I have written, creating this dictionary was more a test of will and stamina and an exercise in project management than mere writing. And although I have managed organizations of up to 80 academics, nothing is more like herding cats” than motivating an international collection of almost 200 distinguished engineers, scientists, and educators scattered around the globe almost entirely via email. Yet, I think there is no other way to undertake a project like this. I still marvel at how Noah Webster must have managed to construct his English Dictionary without the benefits of modern communication. But this project, as much as it is a monument to individual will, is really the collaborative work of many brilliant and dedicated men and women. This is their ictionary and your dictionary

INTRODUCTION
MICOM P120, P121, P122
and P123 relays have been designed to provide more functionality in terms of protection, measuring, automatic operation and order control in any medium voltage electric networkThese relays can be used in industrial and distribution network applications, as well as in high voltage and extremely high voltage protection applications. The specific nature of these relays makes it possible to respond to the various cases of application: energy intake, medium voltage subscriber, cable outlet, overhead line
The earth and phase protection functions comprise instantaneous information and time delay information. The first can be used in logic blocking diagrams so as to optimise the performance of the protection schemes, thus reducing triggering times
The second can be either of the constant type or of the dependent type (IEC, ALSTOM, ANSI/IEEE and C0). This wide choice of characteristics of triggering times makes it possible to easily adapt these relays to an existing protection scheme, irrespective of the other relays already installed on the network
