Smart MV Auto Recloser
Smart protection for faster fault isolation and more resilient distribution networks. The SMARTECH SAR, the Smart MV Auto Recloser, is UTEC's intelligent three-phase vacuum switching and protection solution for overhead medium-voltage distribution networks and distribution substations. By integrating protection, measurement, communication, fault detection, automatic reclosing, and online monitoring in one outdoor platform, SAR helps utilities isolate temporary and permanent faults, restore healthy feeders, reduce outage duration, and strengthen distribution-network resilience.
Key Product Features
Smart Protection and Automation Platform
SAR integrates control, protection, measurement, communication, fault detection, automatic reclosing, and online monitoring to support modern feeder automation and utility distribution-management strategies.
Saudi Energy Approved and Locally Manufactured
A utility-focused solution manufactured in Saudi Arabia to support Saudi Energy requirements, Saudi Vision 2030, and the Kingdom's local-content and industrial-development priorities.
Dual-Voltage Utility Coverage
One product family supports 17.5 kV class equipment for 13.8 kV systems and 36 kV class equipment for 33 kV systems, helping utilities standardize intelligent protection across key distribution voltages.
Vacuum Interruption and Magnetic Actuation
Vacuum interruption works with a high-performance permanent-magnetic actuator to deliver dependable opening, closing, fault interruption, and automatic reclosing with low maintenance requirements.
Advanced Protection and Reclosing Logic
The controller supports instantaneous, time-overcurrent, negative-sequence, directional overcurrent, earth-fault, sensitive-earth-fault, overvoltage, undervoltage, cold-load pickup, hot-line tag, zone-sequence coordination, and programmable IEC/IEEE curves.
ADMS and Communication Ready
Communication options include RS-232 and RS-485 ports together with DNP3.0, Modbus, IEC 60870-5-101, and IEC 60870-5-104 options, enabling integration with utility automation and supervisory platforms.
Reliable Outdoor Performance
The powder-coated 304-grade stainless-steel tank, epoxy-resin insulated poles, integrated sensors, robust enclosure, and wide environmental ratings support long-term operation in demanding outdoor conditions.
Intelligent Monitoring, Protection and Control
The intelligent controller equips SAR with the protection, automation, records, and network data required for modern distribution management. Available capabilities include: instantaneous, time-overcurrent, negative-sequence, directional overcurrent, earth-fault, and sensitive-earth-fault protection; overvoltage and undervoltage protection, cold-load pickup, hot-line tag, and zone-sequence coordination; ten programmable ANSI/IEC protection curves and configurable reclosing times and dead times; phase-current, phase-voltage, frequency, active energy, reactive energy, and power-factor measurements; sequence-of-events recording for 10,000 operations, plus fault and normal-operation records; and communication options for ADMS/SCADA integration through supported serial ports, utility protocols, and optional modem connectivity.
