Mars-Energo Reference standard meter Energomonitor - 3.3T1 is a specialized energy monitoring device used to track and measure energy consumption in industrial settings. This high-precision monitor provides real-time data, allowing users to analyze energy usage and optimize performance.
Functionality and options
Measurements :
Measured values
Testing of Meters :
EM 3.3T1 provides for performance and accuracy testing of electric energy meters (class 0.5 or less accurate). Test results acquired from up to 200 meters (up to 10 measurements per test) can be kept in the internal memory. With EmWorkNet, test results are loaded to a PC for viewing and managing. Test reports are generated automatically.
Testing of Current and Voltage Instruments transformers :
In this mode, EM 3.3T1 works as a comparator and provides for testing of voltage transformers (class up to 0.2) and 1A or 5A current transformers (class up to 0.25). The internal memory can store test results from up to 200 CTS and/or VT's. Automatic report generation and log management functions are available with Transformer Test software.
