Neutral Grounding Transformers and Systems
Acutran has developed a number of designs for neutral grounding transformers and systems. Applications include three-phase zig-zag grounding transformers for utilities, mines, and other power systems. These transformers can also be used for high-resistance grounding which is becoming increasingly important.
Grounding transformers are typically used to provide a relatively low impedance path to ground, which maintains the system neutral at or near ground potential. They can limit the magnitude of transient over voltages when re-striking ground faults occur, as well as provide a source of ground fault current during line-to-ground faults. In addition, neutral grounding transformers and systems can permit the connection of phase to neutral loads when desired. Neutral grounding transformers such as these can be single- or three-phase to protect equipment from faults. All of Acutran's neutral grounding units are built with UL recognized insulation systems to meet the requirements of numerous applications.
Acutran's neutral grounding transformer and system offerings and applications include:
- Three-phase zig-zag grounding transformers, both continuous duty and limited duty
- Three-phase applications include electric utility power systems, mine power systems, commercial power systems, and high-resistance grounding
- Single-phase grounding transformers and grounding systems for electric utilities and other users
Acutran's extensive library of over 5,000 validated designs means we can reduce time and risk for our customers. Unlike other transformer manufacturers who can be slow to respond, Acutran provides a two-day turnaround on most quotations, and often delivers new design and approval drawings within three business days.
