Three-Phase Reference Standard Meter with RS232 for Stationary
Meter Test Systems
This Wide Current Range Three-Phase Reference Standard Meter is
specially designed for use with Stationary Three-Phase Energy Meter
Test Systems. It delivers high accuracy up to 0.05%, making it
ideal for precise energy meter calibration and testing.
Key features
Supports 3-phase 4-wire and 3-phase 3-wire testing configurations Measures active power, reactive power, and cross-connection
reactive power Accurately measures voltage, current, phase angle, frequency, and
power for each phase Calculates phase-to-phase angles, sum of active power, and sum of
reactive power Test data can be easily managed and transferred via RS232 interface
to a computer for further analysis
This high-precision meter is perfect for power utilities,
calibration laboratories, and manufacturers requiring reliable and
efficient three-phase meter testing solutions.
