BS EN IEC 62057-3:2024

This standard BS EN IEC 62057-3:2024 Electrical energy meters. Test equipment, techniques and procedures is classified in these ICS categories:

• 17.220.20 Measurement of electrical and magnetic quantities

IEC 62057-3:2024 applies to an automatic meter testing system (AMTS) permanently installed in a controlled environment. It covers the functions, technical requirements and acceptance methods of an AMTS. It also applies to a newly manufactured AMTS to test static active or reactive energy meters on 50 Hz or 60 Hz networks with an AC voltage up to 600 V (phase to neutral). This document defines the kind of AMTS that can continuously and automatically carry out all the test items specified in IEC 62058-31, including visual inspection, AC voltage test, no-load condition, starting current, accuracy and meter constant test. This document does not apply to: • data interfaces to the meter and test procedures of data interface; • industrial controllers, industrial personal computers, and servers supplied along with the AMTS.
