Product description
Epoxy resin cast dry-type grounding transformer, this product is a neutral point insulated power grid with an artificial neutral point, which is grounded through an arc suppression coil, resistor, or direct grounding. Compensating for single-phase grounding faults in the power grid can prevent the expansion or even eliminate accidents, ensure the quality of power supply, and can be widely used in domain network substations or power plants.
Advantage
-Suitable for three-phase, 50Hz, 6KV, 10KV, and 35KV power grids;
-Mainly used to provide manual and load carrying neutral points for ungrounded neutral point systems for system connection;
-F-class insulation, suitable for indoor use, can also be used after installing a casing;
-Grounding transformers are used in medium point insulated three-phase power systems to provide an artificial neutral point for such systems. The neutral point can be directly grounded or passed through
Grounding of reactors, resistors, or arc suppression coils.
