WM5 96 is a Smart Power Quality Analyzer, while PQT H is
its corresponding transducer version. Both of them are
powered with ARM technology which improves
significantly the signal processing and the communication
speed compared to any other standard analyzer. The
superior features of these new meters are the right answer
to those applications where performances and high
accuracy are a MUST. Both WM5 96 and PQT H are
modular and flexible so to be suitable to the most
demanding applications. They offer many advantages and
solutions that can be summarised in:
• Revenue grade and revenue approval to be used also for
billing purposes thanks to their 0.2 accuracy class and the
compliance to ANSI/IEEE C12.20-1998 and CAN3-C17-M84;
• Real powerful cost control: complex and complete tariff
management (12 tariffs by 24 time periods/day);
• Extended load or line control with asymmetry, phase
sequence and phase loss functions: on up to 16 selected
variables linkable to up to 16 independent or
OR/AND/OR+AND logic controlled alarms;
• Complete interfacing capability: up to 12 digital inputs, up
to 16 pulse outputs, up to 8 analogue outputs, RS232,
RS485, or optical communication.
