Object and purpose of research. Mooring tests of AC gensets are performed using loading devices (loadbank) with pre-set power coefficient. This paper studies water-cooled elements (solenoids) developed to ensure acceptable mass and size of loadbank. The purpose of this study is to assess heat emission losses in clamping solenoid pins of new design, installed into the solenoid active-inductive to enhance reliability and ease of manufacturing. Materials and methods. Active-inductive parameters calculation are performed as per know recommendations for sole-noid. Magnetic induction distribution over the solenoid axis is determined as per Biot-Savart-Laplace law. The plots are given for magnetic induction along the axis of solenoid with different length/diameter ratios. Heat emission of solenoid clamp is assessed taking into account the surface effect in the newly designed loading device. Main results. Heat emission was calculated for the pins made of copper, aluminium and steel. Conclusion. This paper analysed whether clamping pins of newly designed solenoids are practicable to make of stainless steel.
