Introduction
An increasing number of non-linear loads, such as computers, office equipment and frequency
converters are currently being connected to the public electricity distribution network. Electrical
equipment of this type affects the power quality in the network in a negative way and is frequently
more sensitive to disturbances than older equipment. For these reasons, it has never been more
important to measure and monitor power quality in the electricity distribution network, in order to
detect disturbances before serious and costly faults occur.
PQ Secure is the result of targeted efforts by Unipower and our customers to create an advanced,
user-friendly and reliable power quality monitoring system.
PQ Secure consists of three main components; the recorder, communication equipment and a
specially designed analysis and evaluation program, PQ Secure. The PQ Secure system uses a
standard database to store all measured data. This means that advanced analyses have become
possible, opening up completely new evaluation opportunities.
In order to simplify the use of your PQ Secure system we have divided the documentation into three
separate manuals:
PQ Secure Installation manual describes the installation procedures for the recorders and the
system’s software
PQ Secure User manual describes the configuration and use of the system’s software
Technical manual describes how the recorders and the system works from a
technical viewpoint and which parameters are stored
