HS-6303 THREE PHASE ENERGY METER TEST BENCH-16 Position
SUIT FOR CT METER
1.OVERVIEW
HS-6303 three-phase energy meter testing bench adopts SPWM digital power
source technology, comprises high-grade standard digital watt-hour meter, multi-path voltage transformer,
can implement multi-station high accuracy error testing.
This testing bench configurates humanized PC processing software, can provide integrated solution of the energy meter automatic check. Meanwhile, it
provides the requested DLL of the second development, has improved
the self-control and management for the bench by the customer.
This testing bench can be widely used for the energy meter
measurement and testing in electric power, water conservancy,
traffic transportation and colliery departments, as well as the
energy meter testing and production of the energy meter
manufacturer.
This series of the testing bench can test all kind of single phase energy meters, single phase
multi-function meters, single phase intelligent meters, other
meters with special wiring and ANSI standard meter. It is an ideal
new generation multi-station energy meter testing device.
