Denka® Platinum Plate — Engineering Documentation

Fast-switching power electronics inject conducted emissions in the CISPR 11 band (150 kHz – 30 MHz). Peer-reviewed studies associate this distortion with increased losses in induction motors, distribution transformers and cables, accelerated insulation ageing and bearing damage. The Denka® Platinum Plate exploits the frequency-dependent complex permeability of DT400L ferrite: negligible interaction at 50/60 Hz, resistive absorption across the HF band. Independent characterisation at KU Leuven / EnergyVille (Nov 2022) measured 13–15% (≈1.2–1.4 dB) attenuation per plate at 25–30 MHz. Field deployments across 100+ facilities typically show 8–15% reduction in specific energy consumption (kWh/ton), up to ~20% at select sites, verified with IPMVP Option B/C.^{[1[1] IEC CISPR 11:2024Industrial, scientific and medical equipment — Radio-frequency disturbance characteristics — Limits and methods of measurement.,5[5] Aarniovuori et al., IECON 2013Induction motor losses under converter supply (+8.7% to +19% total losses).,8[8] Yaghoobi et al., 2020Distribution transformer eddy-current losses and insulation ageing under inverter harmonics.,12[12] Erdman et al., 1996Effect of PWM inverters on AC motor bearing currents and shaft voltages.
