First steps in the production of fully electronic automatic electricity metercalibration systems were made 10 years ago by KAIPU. The system described and offered here comprises components based on most modern technologies. It therefore combines long term experience in this field with the application ofstate of the art technology.The recently developed new software is based on KAIPU 's historical experience in providing various testing solution to numbers of manufacturers, Utility companies, Metrological institutes etc.The following electricity meters of the accuracy classes 0.2, 0.5, 1 and 2 can be tested:*2 wire-, 3 wire- and 4 wire meters for active and reactive energy(true and cross-connected). * KP-S1000 Single phase energy meter test bench* KP-S3000 Three phase energy meter test bench* KP-S4300 Withstand voltage test bench* KP-P1001-C Portable single phase energy meter test bench* KP-P3001-C Portable three phase energy meter test bench* KP-S1100 Single phase aging and counting register bench* KP-3100 Three phase aging and counting register bench* KP-1100 Reference meter 0.02% or 0.05% class* KP-S3000 compatible function for test 1ph and 3ph energy meter,Digital and machinery energy meter test bench
