UNI-T Intelligent 3 Phase Clamp Voltammeter (UT267B)

The UT267B is an intelligent three-phase high-precision digital phase voltammeter specially designed for measurements in industrial operating conditions. It is a fully automatic, multi-purpose device with low power consumption and simple operation. You can measure circuits without disturbing them, the device is 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 device 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 device allows to store up to 99 sets of measured data in the internal memory, which 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.
