Coupling capacitors, connected phase-to-ground in both solid and isolated neutral systems, serve multifaceted purposes, from filtering transients during faults to facilitating signal coupling within the system, including the ability to filter specific tuned frequencies if desired. Our engineering team excels in making personalised solutions tailored to a wide range of applications.
