ELEQ Choke module for supressing ferro-resonance
ELEQ Choke module for supressing ferro-resonance
In three-phase current networks with an isolated neutral point, ferro-resonance can occur due to the interaction between the non-linear inductance of single-pole current transformers in open-circuit operation and the network's earthing capacitance. This phenomenon can lead to overheating and overvoltages, necessitating protective measures.
- Choke Module (BE) for Suppressing Ferro-resonance: Designed to protect single-pole current transformers by preventing overheating and overvoltages.
- Wiring Diagram: Provides the configuration for connecting the choke module to the network.
- Types and Ratings: The choke modules are available in various types (BE2, BE4, BE6, BE9, BE10, BE15) with nominal three-phase current ratings of 2A, 4A, 6A, 9A, 10A, and 15A respectively.
- Power Ratings: Total power ratings are specified as 147W or 295W, with corresponding total power dissipation (P D total) of 178W or 356W.
- Voltage Ratings: Nominal voltage is 100V, with an operating voltage range of 100...110V and an isolation level of 0.72kV.
- Frequency: Standard frequency is 50Hz, with other frequencies available upon request.
- Insulation Class: Class E insulation is used.
- Physical Specifications: The case is made of steel, with dimensions of 222x190x229mm and a grey color.
Details for ordering the choke modules are provided, ensuring the correct selection based on network requirements.

\ mastering electricity BE - Choke module for suppressing ferro-resonance In three phase current networks with isolated neutral point which use single-pole current transformers, ferro-resonance may occur. These resonances are generated by the concur of single-pole current transformers non-linear inductance of open-circuit operation and the earthing capacitance of the network. In order to protect the single-pole current transformer from overheating and to avoid possible overvoltages, the en-winding of the transformer should be constantly vaporised.
