Abstract

An apparatus and method for batch testing of electric power controlling or monitoring metering devices are disclosed. The apparatus comprises a PC, a batch testing controller, a signal source generator, an automatic positioning component and a serial server component, wherein the batch testing controller comprises a CPU plug-in, a switching value input function plug-in, a switching value output function plug-in, and a signal function plug-in. The CPU plug-in controls the switching value input function plug-in, the outlet function plug-in and the signal function plug-in connected with the CPU plug-in by receiving commands of the PC, the switching value input function plug-in, the outlet function plug-in and the signal function plug-in are connected with metering devices to be tested through fixing devices to test current, voltage, power factors, switching value input function and switching value output function of the metering devices to be tested. The serial server component receives the test results through a 485 communication interface and feeds back the test results to the PC. The apparatus and method have the advantages of being time-saving and convenient, high in automation level and high in reliability, and are widely applicable to batch production and testing of electric power metering devices.
