H&S is a technology, engineering, and system integration partner for digital substations, power transmission and distribution systems, and modern secondary technology.

H&S supports utilities, grid operators, and equipment manufacturers throughout the lifecycle of substation automation projects – from engineering, production, and system integration to testing, commissioning, and training.

A key focus is IEC 61850. The solutions enable manufacturer-independent SCL engineering and validation for complex protection, control, and automation systems. We support manual and fully automated testing using IEC 61850 and IEC 60870-5-104, with additional protocols integrated as required. Combined with the IPS-20 process simulator, our solutions enable closed-loop testing from simulated process signals through the hardware interface and back, providing comprehensive validation of the automation chain.

As a system integrator, H&S plans, designs, builds, and commissions complete secondary systems for high- and extra-high-voltage substations. The expertise covers protection, control, and substation automation, combining practical project experience with in-depth knowledge of international standards and digital technologies.

By combining system integration with own engineering and testing solutions from H&S, consistent workflows across the entire project lifecycle are created – enabling reliable, interoperable, and future-ready substations and supporting the digital transformation of transmission and distribution networks.
