Information about their widespread use comes to us from the 70s of the XIX century. Dolivo-Dobrovolsky can rightly be considered the founding father of relay protection. The rectangular devices are test connection blocks, used for testing and isolation of instrument transformer circuits. In 1901, the induction-type overcurrent relay was introduced, followed by ASEA (now ABB) launching the first time-delay overcurrent relay, TCB, in 1905, enabling graded protection. He is one of the best-known experts in electrical protection and control engineering in German-speaking countries.
