Core Features
Dual winding comprehensive protection: covering differential, overcurrent/grounding faults, overvoltage/undervoltage, overexcitation, inrush current lockout, overload, etc., microprocessor driven fast action (about 10ms), suitable for complex working conditions of dual winding transformers.
Flexible Expansion and Programming: FlexLogic ™ Technical support for custom protection logic, 5 channels of 4-20mA analog output can be connected to DCS/PLC, 16 channels of digital input are compatible with external signal linkage, and 6 programmable relays meet control requirements such as tripping and alarm.
Enhanced human-computer interaction: 40 character LCD large screen+LED indicator lights+numeric keypad, supporting local parameter settings, fault diagnosis, and event record tracing, with a pull-out structure for easy maintenance and replacement.
Accurate state monitoring: Real time collection of parameters such as current, voltage, power, frequency, temperature, etc., supporting waveform recording, trend analysis, and pre fault data tracing for easy maintenance and analysis.
Universal working condition adaptation: Standard coating design, suitable for conventional industrial environments, wide range power supply to meet the power supply needs of most power/industrial scenarios.
Application scenarios
Main or backup protection for double winding power/distribution transformers in power systems, industrial power grids, renewable energy, etc.
Transformers in industries such as chemical, metallurgical, and mining are used for comprehensive protection of transformer windings, iron cores, and electrical circuits.
A dual winding transformer system that does not require conformal coating and has a wide range of control power supply in a conventional industrial environment.
