Recently (reported by this website) --- the post-project acceptance conference for the high voltage and ultra-high voltage complete protection system R&D (increment 1) project of iESLab was held in its headquarters in Jinan. The seven types under the three product categories of 220kV and 500kV substation line protective device, transformer protective device, busbar protective device in iESLab passed the tests of national certification authorities and were conferred with reports of type tests, dynamic simulation test and conformance test. The R&D completion of the three main devices signifies a major milestone breakthrough by iESLab in the field of electric power automation high voltage protection.

The product technology of high voltage and ultra-high voltage protection occupies a core position among the substation automation technologies; moreover, in the aspects of its protection principles and properties, protection analysis and research methods, hardware and process, and operational management and test maintenance, this product technology of high voltage and ultra-high voltage protection represents the most advanced technical strength and the highest level in the current industry and is a necessary technology for a company to enter into the first echelon of plant and substation automation market.
