Neutral Grounding Transformer can be explained as a single phase transformer primary with (high voltage) rated voltage, and phase to the neutral voltage are equivalence additional the range of the secondary (lower voltage) either 110V or 240V .
Neutral grounding transformers in arrangement of resistance grounding resistor insulate power transformers and generators, from prejudicial omission currents.in order to operate the protective fault clearing relays and current transformers, less resistance grounding of unbiased outright the field oversight current to a high level (up to 50 amps or more).the components are then further used to immediately clear the blunder, maximum with in few seconds.
The feature of defined current and fast reply time even prohibit over heating and mechanical stress on conductors.the voltage rated up to 400 amps for 10 seconds for low resistance grounding resistors and are basically remain at medium voltage system. The grounding transformers are typically required to lower the voltage reflected to the neutral grounding resistor, to prevent the Ground fault protection for high voltage transformer and generator grounding.
The designing of Post Glover's GT for processing is up to 15kV primary. Typically resistors are designed according to the need of customer where as voltages are basically 240V. A secondary resistor mounted in a common enclosure with in the typical construction of dry type transformer.
- stainless steel grid resistor banks standard
- Optional Edgewound resistor banks (application dependent)
- Dry Type Transformer
- Mill Galvanized Type 3R enclosure
- Extra heavy duty mounting channels for transformer
- Junction box/ Terminal block for easy addition of protective relaying equipment
