Synopsis of the talk:

The first commercial bulk-oil circuit breakers appeared on the market around 1910 with manufacturing in North America dominated by GE and Westinghouse. Current interruption was viewed as an AC event for almost two decades and, with no short-circuit test laboratories, commissioning on-site often included a fault test which resulted in failure. The existence of TRVs was first proposed in 1927 and proven in 1931. TRVs evolved driven by experience and breaker performance. The first IEC standard for breakers was published in the 1950s and the today’s IEEE standard did not start until the early 1970s. The history of TRVs and standards is not only about the subject itself but also of those who contributed to the development.
