II. Introduction
The
Digital 3-Phase Voltammeter,
the latest product in clamp meter series, is a
digitalized, multifunctional, high-precision and intelligent multi-parameter
industrial-frequency measurement instrument.
Designed with latest
microprocessor technology and digital signal processing technology, UT268B can
measure industrial-frequency parameters (i.e. voltage, RMS current,
active/reactive power, apparent power, industrial frequency, power factor, phase
relation, and others) in direct AC sampling method, identify transformer connection
section and inductive and capacitive circuits, test secondary loop and bus
differential protection system, display phase relations between current
transformers under differential protection, and check if the wiring of electric energy
meter is correct. By using clamp current transformer, this voltammeter can perform
measurement without disconnecting from measured conductor, making it a safe,
accurate and portable electric power meter.
Digital 3-Phase Voltammeter
, also known as
intelligent 3-Phase Voltammeter
,
Multifunctional 3-Phase Voltammeter
,
Digital Clamp Voltammeter
, etc., is
suitable for use in electric power, petrochemical industry, metallurgy, railway,
industrial and mining enterprises, scientific and research institute, metrology
service, electric energy charging system, relay protection system, and more.
III. Functions Introduction
1. Devised with large screen with high-brightness backlight, to clearly display
working state and testing parameters.
2. The ability to measure 3-phase voltage, current, phase, frequency, active power,
reactive power, apparent power, power factor, and overall power.
3. Can be used to measure grid frequency and phase sequence.
4. The function of phase measurement under small current of 5mA allows for
checking wire connection without load.
5. Automatically identify transformer winding and capacitive and inductive loads;
and identify wrong connection of 3P3W and 3P4W.
6. Static storage function to enable store 500 groups of data at most.
