Add to Cart
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.
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.
