In this version of Advanced Supervision without discharge with vampire voltage tapping, a small perforation is made in the insulation of the cable until it contacts the conductor, without affecting the integrity of the installation. As with the other LRS models, the current is measured by means of open core transformers. It is a universal solution, compatible with any base or switch.

This new product has the following features:

• Live installation
• Compatible with any LV Panel, brand and type of fuse switches and circuit breakers
•  Same electronic cards of our other solutions such us Smart Fuse Switches.
•  Same performance of our other supervisors, including measurements per line and phase
• Cabling concentrated in each line, no cable on the ground
• Flexible location of each component on the energy cables
• Fast installation
• The solution is compuesta by a feeder meter case, current transformers, voltage taps  and voltage cables.

Advanced Line Supervisor (SAL)

Inside this supervisor (SAL) is assembled the TSA feeder meter (Advanced Supervision Card). This three phase meter reads all the
electrical parameters and send them to the LV Remote unit through RS485 serial bus ports.

It includes built-in current transformers and a voltage taps per phase.
Available current transformers with different current ratios, based on fuse switches amperage.

The Smart Fuse Switch with the Lower Solution consists of a fuse switch, a SAL (Line Advanced Supervisor) which is assembled beneath the fuse switch, and a feeder meter. These fuse switches can incorporate the entire range of Pronutec accessories and terminals.

FEATURES

• Three phase supervisor per outgoing
• Built-in Current Transformers / Voltage taps
• Compact design & very few cabling
• Protection fuses
• Permits replacement of feeder meters on tension, no need of switching off
• Possible Retrofit of existing fuse switches

TSA (Advanced Supervision Card)

The feeder meter is assembled inside of the Supervisor (SAL). It’s a three phase meter which reads all the electrical parameters and send them to the LV Remote unit through RS485 serial bus ports.

SAL (Line Advanced)

It includes built-in current transformers and a voltage taps per phase.
Available current transformers with different current ratios, based on fuse switches amperage.

SFS upper solution consists of a fuse switch, protection case on top of it, current transformers, voltage connections and feeder meter.

FEATURES:

• Compact design & very few cabling
• Protection fuses
• Permits replacement of feeder meters on tension,
  no need of switching off

The Gorwin Bypass Changeover Switch allows maintenance or replacement of the main changeover switch without interrupting power to the load. It provides a safe and convenient way to transfer supply between Main, Bypass, and Load—ensuring continuous operation in critical applications.

The Bypass CHO uses a three-position changeover plus an integrated bypass path with mechanical interlocking, allowing the load to remain energized while the main switch is serviced.

How It Works

A dedicated bypass path allows the load to be powered while the main switch is isolated.
Integrated mechanical interlocking ensures only one path is active at a time, preventing wrong operations and enhancing safety

Key Benefits

• Continuous Power During Maintenance
• Safe Transfer Between Main, Load, and Bypass
• Mechanical Interlocking for Fail-Safe Operation
• On-Load Switching Capability
• Same High Performance as Standard CHO
• High breaking & making capacity
• Compact & Robust Design
• IEC 60947-6-1 Compliant
• Enclosed solution is available
• Available with direct handle and panel handle.
• Wide range of accessories: auxiliary contacts, phase barriers, terminal shroud etc.

Applications
