SUMMARY
The discussion focuses on designing a coil for a 24V DC application with a maximum power rating of 200W, specifically for use in 33kV VCBs as a tripping coil. Key parameters include the coil gauge, number of turns, and inner and outer diameters (ID & OD). Participants emphasize that coils should be rated by inductance, DC resistance, and saturation current rather than power alone. The acceptable series resistance for the circuit is noted to be 2.9 ohms.
