Scope
This document applies to fixed power meter test devices (MTUs) permanently installed in laboratories for power meter testing and calibration, particularly for type testing, acceptance testing, and verification testing of the devices. This document covers the requirements for automated MTUs used in indoor laboratories, and is applicable to newly manufactured MTUs used for testing power meters operating in AC voltage networks with a maximum voltage of 600 V (line-to-line) and a frequency of 50 Hz or 60 Hz. If the power meters are used in system voltages not specified in this document, the special requirements for MTUs shall be negotiated between the manufacturer and the purchaser. This document also defines the types of tests for MTUs, including type testing, routine testing, acceptance testing, and commissioning testing. This document does not apply to: - Portable reference power meters and portable sources; - Power meters; - Data interfaces of power meters and the test procedures for these interfaces; - Transformers connected to MTUs; - Personal computers supplied with MTUs.
