WebMay 12, 2024 · 3. Common earthing through an earthing transformer on the busbar. An effective and often cheap way to make sure that the system always is correctly earthed is to connect any earthing transformer to the busbar. See Figure 4 which shows the same network as in Figure 1 but with an alternative method of earthing. WebJul 30, 2007 · There are even grounding wires going from a trnsformer core to ground in most installations. The grounding of CT secondaries is done for many reasons. One is that capacitive coupling between a HV busbar and the CT secondary is a reality. In some transformers, the capacitance is quite high and the resulting common mode voltage …
