Zig-Zag Grounding Transformers for Photovoltaic Systems

More and more solar providers are running up against the need to provide effective grounding as requested by local utility companies. Acutran has been manufacturing custom-engineered transformers to meet these requirements with our zig-zag grounding transformer.

When designing these transformers, careful consideration is given to customer requirements such as:

  • X/R Ratio Values
  • Impedance/Ohm Calculations
  • Continuous Current Requirements
  • Fault Current Values and Duration

Our custom-engineered transformers are built around high-grade components  and processes and customer-driven design parameters:

  • Silicon Steel
  • Copper Wound Components
  • VPI – Vacuum Pressure Impregnation
  • Custom or Standard Operating Temperatures
  • Custom Terminals/Connections
  • 600V Class UL-Recognized Insulation Systems for 200° and 220°
  • NEMA 1 Floor Mount or Wall Mount
  • NEMA 3R Floor Wall Mount
  • Condensation Reducing Strip Heater(s) and Thermostats
