Technical data
Filter resistors are offered in voltage of 12 / 17.5 / 24 / 36 / 52 / 72.5 kV in IP00 and IP23. Filter resistors are used in in power grids to improve the quality of the grid by filtering out higher harmonics. In many cases filter resistors need to comply with local directives. Danotherm offers filter resistors that comply with CIGRE WG 14.30 section 17 (specifications and design for AC filter in HVDC applications), IEC 60071-1 (insulation coordination) and IEC 60529 (Ingress Protection)
