The lower voltage winding should be excited, in most cases, to some multiple of its rating. For example, if the transformer in Fig. 50 is rated 115.5 kV to 7.2 kV, energize the low-voltage winding to 7.2 V, then measure voltage on the high-voltage winding. The high side should be 1/1000 of its rating, or 115.5 V.
Aug 17, 2021 · Global Containerized Substation Market Dynamics-Low cost and low startup time because of short installation and commissioning period on-site acts as a driver to the growth of the Global Containerized Substation Market. The needs for the site infrastructure, camp, specialists, and traveling are substantially reduced.

Jan 28, 2021 · Commissioning the HVAC system was very complex because it involved measuring the correspondence of the HVAC system to the design requirements. Therefore the temperatures at various points in the substation were measured and then the equipment involved was calibrated in order to obtain a thermal and air flow balance.
Oct 06, 2021 · A quick reminder to substation transformer basics and safety dos and don'ts The substation transformer is static equipment, which converts electrical energy from one voltage to another. As the system voltage goes up, the techniques to be used for the design, construction, installation, operation, and maintenance also become more and more critical.
