Description
Introduction:
ETCR4100 pair of pliers digital phase table is my company has a well- developed specifically for field testing of various phases
of the instrument , with high accuracy, high stability, low power consumption, easy to use features . Can be measured directly in
the case of the circuit under test is not open between the two voltages , currents and phase voltages between the two currents
between , in addition, you can also determine the phase sequence of the three-phase transformer connection group , inductive,
capacitive circuits , test secondary loop and bus differential protection system , read travel protection CT phase relationship
between the groups , check the meter wiring is correct or not .
ETCR4100 double clamp digital phase meter with large LCD display with blue backlight , display clear, exquisite and
luxurious appearance.
ETCR4100 pair of pliers digital phase table for the power , petrochemical, metallurgy , railway , meteorology, industrial and
mining enterprises , scientific research institutions , metering sector.
