This part of the IEC 60255 series specifies minimum requirements for thermal protection relays. This standard includes specification of the protection function@ measurement characteristics and test methodologies. The object of this standard is to establish a common and reproducible reference for evaluating dependent time relays which protect equipment from thermal damage by measuring a.c. current flowing through the equipment. Complementary input energizing quantities such as ambient@ coolant@ top oil and winding temperature may be applicable for the thermal protection specification set forth in this standard. This standard covers protection relays based on a thermal model with memory function. The test methodologies for verifying performance characteristics of the thermal protection function and accuracy are also included in this Standard. This standard does not intend to cover the thermal overload protection trip classes indicated in IEC 60947-4-1 and IEC 60947-4-2@ related to electromechanical and electronic protection devices for low voltage motor-starters.
Measuring relays and protection equipment - Part 149: Functional requirements for thermal electrical relays
This International Standard defines a format for files containing transient waveform and event data collected from power systems or power system models. The format is intended to provide an easily interpretable form for use in exchanging data. The standard is for files stored on currently used physical media such as portable external hard drives, USB drives, flash drives, CD, and DVD. It is not a standard for transferring data files over communication networks.
