0.05 Class Three Phase Electric Meter Test Bench
Major Application and Functions:
1) Touch screen operation for control source panel
2) With standard meter together show all necessary parameters in
one screen
3) Majorly used in automatic meter calibration setup (connect and
disconnect of meter)
4) Calibration setup include two types: fixed load point and load
point changing
5) Calibrate the meter through Genus software by applying control
protocol offered. 6) With good power stability and high accuracy
output
7) Can switch power factor between 1.0 and 0.5L, also phase angle
can set & edit by end user. 8) Can switch four different balance &
unbalance conditions 9) Independent output for each phase including
voltage & current
10) Can ensure constant power output between connect and disconnect
of meter. 11) Protection: current open circuit and voltage short
circuit, etc 12) With PC communication port RS232
Output & Build time
Power build time for fixed load point setup: within 5 seconds Power
build time for load change setup: within 10 seconds Power
stability: 0.02% (value in the range) after power build
Set value to output value: Range ±0.05%, for P, Q, S, V, A, PF
