kode relay - is a relay thast controls the extensibility automatic closing and reclosing of a dc circuit interrupter generally in response to load circuit conditions 83 Automatic Selective Control or Transfer Relay is a relay that operates to select automatically between certain sources or conditions in a equipment or performs a transfer operation automatically 84 There are two methods for indicating protection relay functions in common use One is given in ANSI Standard and uses a numbering system for various functions The functions are supplemented by letters where amplification of the function is required The other is given in IEC 60617 and uses graphical symbols PDF ANSI Standard Device Numbers Common Acronyms GE Vernova Decoding ANSI Codes for Protection Relays GoSwitchgear In electric power systems and industrial automation ANSI Device Numbers can be used to identify equipment and devices in a system such as relays circuit breakers or instrumentsThe device numbers are enumerated in ANSIIEEE Standard C372 Standard for Electrical Power System Device Function Numbers Acronyms and Contact Designations Many of these devices protect electrical systems and ANSIIEEE Function Number Codes Electric Power Measurement and Kali ini saya akan ulas tentang arti kodekode pada relay Mungkin sobat smart pernah perhatikan pada sebuah relay ada beberapa kode dan mungkin masih bingung mengenai apa arti kodekode itu dan untuk apa semua itu di tuliskan pada relay Kodekode yang paling banyak ditemui adalah kode angka disetiap kaki terminal relay Yakni angka 30 87a 32 Kode ANSI Proteksi Tenaga Listrik Beserta Relay Dan Fungsinya It is typical to find multiple functions performed by a single device in an electrical power system Function Codes for Overcurrent Protection Relays A common example of this is an instantaneoustime overcurrent relay a single device monitoring the signals coming from a set of current transformers CTs commanding a circuit breaker to trip tl289 if the current exceeds a predetermined limit for ANSI Codes Device Designation Numbers EEP GEDigitalEnergycom 3 Device No Description 512 Negative Sequence Time Overcurrent 52 Ac Circuit Breaker 53 Exciter or Dc Generator Relay 54 Turning Gear Engaging Device 55 Power Factor Relay 56 Field Application Relay 57 ShortCircuiting or Grounding Device 58 Rectification Failure Relay 59 Overvoltage Relay 59B Bank Phase Overvoltage 59P Phase Overvoltage 59N Neutral Overvoltage Arti angkaangka pada relay MOTOHOBY ANSI Device Numbers and Acronyms Electrical Volt 40 Field Relay Loss of Excitation 41 Field Circuit Breaker 42 Running Circuit Breaker 43 Manual Transfer or Selector Device 44 Unit Sequence Starting Relay 45 Fire Detector 46 ReversePhase or Phase Balance Current Relay or Stator Current Unbalance 47 PhaseSequence or Phase Balance Voltage Relay Protection functions specified by ANSI codes improve relay reliability reduce the risk of damage and prevent system failure ANSI Codes help identify and troubleshoot relay functions facilitating efficient maintenance and repair activities Relays that comply with the ANSI standards can work with various new or old systems ANSI device numbers Wikipedia Protection Relay ANSI Standards Electrical Engineering Portal Protection Relay ANSI Standards In the design of electrical power systems the ANSI Standard Device Numbers denote what features a protective device supports such as a relay or circuit breaker These types of devices protect electrical systems and components from damage when an unwanted event occurs such as an electrical fault ANSI codes and IEC Relay Symbols Electrical Engineering Kode ANSI Nama Relay Dan Fungsinya ANSI 12 Over Speed Relay Berfungsi untuk mendeteksi putaran lebih dari penggerak mula generator yang disebabkan oleh kehilangan beban atau tripnya PMT ANSI 14 Under Speed Relay Berfungsi untuk mendeteksi putaran generator yang lambat dari putaran nominalnya ANSI 21 Distance Relay Relai jarak akan bekerja fastnas.id dengan cara membandingkan impedansi
