Information about the product documentation set and related documentation available for download.
Lists all available functions, their IEC 61850, IEC 60617, and IEC-ANSI identifications.
Details the evolution of the 615 series IEDs, including new products and platform enhancements across different versions.
Describes the Local Human-Machine Interface (LHMI) which comprises the display, buttons, LED indicators and communication port.
Details the predefined user categories for LHMI and WHMI, their rights, default passwords, and the audit trail function.
Covers the communication protocols supported by the IED, including IEC 61850, IEC 60870-5-103, and Modbus.
Covers analog input settings for phase currents, residual current, and phase voltages, as well as authorization settings and binary input settings.
Describes the IED's self-supervision system, which continuously monitors software and electronics, handling fault situations and informing the user.
Describes the support for six setting groups, parameter categorization, and how to change the active setting group at runtime.
Describes the various types of binary outputs used for tripping, control actions, and indicating signals.
Details the RTD and mA analog input module for monitoring and metering, including functionality, operation principle, and signal type selection.
Covers three-phase non-directional overcurrent protection (PHxPTOC) and three-phase directional overcurrent protection (DPHxPDOC).
Covers non-directional earth-fault protection (EFxPTOC) and directional earth-fault protection (DEFxPDEF).
Provides phase segregated line differential protection for distribution network lines and cables.
Protects two-winding transformers and generator-transformer blocks, including low biased and high instantaneous stages.
A sensitive protection applied to protect the star-connected winding of a transformer, stable for faults outside the protected zone.
Protects electric motors from phase unbalance, detecting large negative-sequence currents.
Covers three-phase overvoltage protection (PHPTOV) and three-phase undervoltage protection (PHPTUV).
Protects network components against abnormal frequency conditions, providing overfrequency, underfrequency, and rate-of-change protection.
Provides protection against excessive starting time and locked rotor conditions, protecting motors from overheating.
Detects failure of the circuit breaker to trip or back-trip, activating a backup trip or retrip signal.
Supervises the control circuit of the circuit breaker, detecting invalidity and reporting failures.
Monitors various circuit breaker parameters like number of operations, energy calculation, and travel times.
Covers three-phase current, voltage, residual current/voltage, sequence, and frequency measurements.
Provides control and status indication for circuit breakers, disconnectors, and earthing switches.
Checks the condition across the circuit breaker for synchronism and energizing, permitting controlled closing.
Provides automatic reclosing shots to clear faults and restore power, with options for programmable shots and delays.
Covers front and rear Ethernet connections, serial connections (EIA-232, EIA-485), and fiber-optic ST connections.
Covers various EMC tests like burst disturbance, electrostatic discharge, and radio frequency interference.
