The Electrocorder series, EC-6VA, is suitable for short- and long-term, three-phase power line monitoring.
It is powered by four, 9 V alkaline batteries and is available in IP65 housing suitable for outdoor use or as an IP43 version for indoor use.
Each instrument has three Rogowski coils and four voltage leads. Storage capacity per phase is 32,000 samples (a maximum of 300 days recording).
There are four models available with maximum line current ranges of 300, 1000, 2000 and 3000 A. Maximum line voltage is 500 V. Sixteen samples per cycle are taken to provide a true picture of troughs and peaks occurring in periods of one cycle or longer.
Stored data is uploaded via a USB cable and, using the supplied Electrosoft program, can be displayed in tabular or graphical format.
