The UNI-T UT267B Intelligent Three Phase Clamp Volt-Ammeter is an intelligent three-phase high-precision digital phase volt-ammeter specially designed for measurements in industrial operating conditions.
The Three Phase Angle Meter – UNI-T UT267B is a fully automatic, multi-purpose device with low power consumption and simple operation.
You can measure circuits without disturbing them and is also able to measure three phase voltage and current, phase angle between voltage and current or between three-phase voltages or currents, frequency, phase sequence, active, reactive and apparent power, power factor, sum of vectors, and is also able identify the connection of groups of transformers, inductive and capacitive circuits, secondary circuits and measurements of the bus differential protection system.
The Three Phase Angle Meter – UNI-T UT267B can also read the differential protection phase between CT units, check and ensure the correct connection of electricity meters. The dot matrix LCD display has 240 dots × 160 dots and allows the display of voltage and current vectors.
The UNI-T UT267B allows you to store up to 99 sets of measured data in the internal memory. These can then be transferred to the PC via the RS232 interface.
The supplied system software enables online real-time monitoring, history retrieval, dynamic display, data reading, storage, reporting, printing, etc. Together, these features provide a safe, accurate and convenient new tool for inspectors and electricians.
