GF302D1S Portable Three Phase Electricity Meter Test System With Reference Meter and Current & Voltage Source

electricity meter test system

The GF302D1S portable three phase electricity meter test system consists of an integrated 0.05% three-phase current and voltage source and a three-phase electronic reference meter of accuracy class 0.02. Characteristic features of the GF302D1S are its wide measuring range from 0 to 3*120A and 0 to 3*600V, high accuracy and high tolerance to unwanted external influences.

 

The GF302D1S potable meter test system allows the monitoring of meter installations as well as analysis of the local mains conditions when it is as portable reference working standard. The equipment offers high functionality combined with an excellent menu guided operation via built-in keyboards and colored 7' touch LCD-display. Voltage & current harmonics output from 2 to 63 times. This model portable meter test system can be programmable by PC, automatic generation of energy meter error test report.
