The development of a combined leakage current sensor of a suspended insulator is presented. Negative factors of the influence of partial discharge currents on suspended insulators are described. The relevance of the development is justified. The requirements for the block diagram of a combined current sensor consisting of a background current sensor and a partial discharge current sensor are formulated. A block diagram of a combined leakage current sensor of a suspended insulator has been developed. A constructive solution for mounting a combined current sensor is proposed. Experimental studies of the upgraded current sensor were carried out. The main components of its layout are presented.
