Isolertrafo for overgang fra IT til TN-S nett

Product catalog summary
Overview: The document provides technical specifications and details for the RT-LI PEN series of isolation transformers designed for converting Norwegian IT networks to European TN-S networks. These transformers create a galvanic separation between the power grid and the outgoing circuit, allowing one phase to be grounded, thus simulating a TN-S network for connected loads.
Specifications:
  • Primary Voltage: 230 V
  • Frequency: 47-63 Hz
  • Secondary Voltage: 230 V
  • Construction Standard: EN61558-2-4
  • Insulation Voltage: 2.5 kV AC RMS
  • Safety Class: I
  • Insulation Class: B (130°C)
  • Maximum Ambient Temperature: 40°C
  • Enclosure Rating: IP44
Product Features: The RT-LI PEN transformers are specially constructed with low-loss technology to suppress inrush currents, making them suitable for connection to standard residential circuits without tripping breakers. They are particularly suitable for applications such as electric vehicle charging that require a TN-S network. The transformers are housed in a tight IP44 enclosure, allowing for outdoor installation.
Connection Diagrams: The document includes diagrams illustrating the primary and secondary connections for both TN and IT networks, with instructions for removing jumpers to switch between network types.
Models and Performance: The document lists several models with varying specifications, including power ratings, current capacities, and weight. Each model is identified by a unique article number.

Isolertrafo for overgang fra IT til TN-S nett-1

Isolertrafo for overgang fra IT til TN-S nett Målskisse Type 1RT-LI PEN Spesialkonstruert isolertransformator for omforming av norsk IT-nett til Europeisk TN-S nett. En isolertransformator skaper et galvanisk skille mellom E-verkets nett og utgående kurs. Dermed kan en av fasene jordes (N-leder) slik at tilkoblet belastning vil oppfatte sekundærnettet som et TN-S nett. 1RT-LI PEN er basert på Noratels lavtapstrafo som har svært lave tap, samt undertrykker startstrømmen slik at tilkobling til normale boligkurser er mulig uten sikringsproblemer. Velegnet til bla. lading av elbil som krever TN-S nett. Tett kapsling IP44, kan monteres utendørs.
