Acoustics — Noise control design procedures for open plant
This International Standard defines the procedures for noise control of mainly open plants.
It is applicable to the following:
_ specification of procedures for noise control during engineering of a new plant and modification/extension of
existing plants (construction noise procedures are outside the scope of this International Standard but should
be considered);
_ definition of responsibilities…
Electrical relays - Part 24: Common format for transient data exchange (COMTRADE) for power systems
Defines a format for files containing transient waveform and event data collected from power systems or power system models. Applies to files stored on physical media such as digital hard drives and diskettes.
