SARAH: PT(Potential Transformer or VT=Voltage Transformer) for PV power conditioner

It is an introduction of the potential transformer for voltage detection with optimized power conditioners for photovoltaic power generation, to demand monitoring system. SARAH Inc. supply transformer to match the customer’s design is available.


SARAH Inc. Potential Transformer

This product is based on the insulated structure of IEC60950.
  • Creepage distance: Over 4mm
  • If the plastic resin material exceeding the tracking resistance 600V is used, performance equivalent to the creepage distance of 8 mm will be guaranteed.
  • The linear characteristic is excellent in the domain of the low voltage.
  • There is little high frequency distortion.
  • Phase difference is small.
