Use this Protection Relay Setting Calculator to calculate pickup current, time multiplier settings (TMS), operating time, coordination time interval (CTI), and plug setting multiplier (PSM) using fault current, CT ratio, and IEC 60255 curve parameters. Protection relays employ a wide range of configurable parameters to identify defects & trip the breaker in a controlled & selected manner. Understanding each setting facilitates proper relay coordination. TSM – Time. This technical report refers to the electrical protections of all 132kV switchgear. All calculations are based on the available documentation/ information.

[pdf] Our relay protection tester offers comprehensive testing for both optical digital and traditional protective devices. It's ideal for power plants, substations, equipment manufacturers, and institutions needing relay protection evaluations. Below is an analysis from the aspects of working principle, technical parameters, application scenarios, industry standards, and. Our conventional relay test set series is developed based on years of industry experience and technological accumulation, catering to various needs of power system relay testing. Versatile Outputs: Supports up to 6-phase voltage/current. Mainly including performance testing, fault simulation, parameter setting, system debugging, teaching, and training. 8 kg and offers 4x300V and 6x20A outputs. Its maximum current can reach 60A, and the output power reaches 200VA/Phase.
[pdf] The widely used United Sates standard ANSI/IEEE C37. 2 'Electrical Power System Device Function Numbers, Acronyms, and Contact Designations' deals with protective device function numbering and acronyms. Even in those parts of the world where IEC standards are predominate, the use of ANSI numbering. These numbers are based on a system that is adopted by a standard for automatic switchgear by Institute of Electrical and Electronics Engineers (IEEE), and incorporated in American Standard C37. These types of devices protect electrical systems and components from damage when an unwanted event occurs, such as an electrical.
