Short circuits between phase and earth can result in irreversible damage to networks and equipment. Earthing resistors from HEINE Resistors limit the fault current that arises between phase and earth as a result of short circuits.
HEINE offers special, project-specific versions in addition to its standard range of Neutral earthing resistors. The following technical data is required for design an neutral earthing resistor:
Our neutral earthing resistors are manufactured as follows:
Nominal voltage | Up to 55 kV (higher voltages available upon request) |
isolation class | Up to 72,5 kV (higher isolation class available upon request) |
Fault current | Up to 10 kA |
Protection class | IP00 - IP55 |
