Why should the core of the transformer be grounded? [Solution] The iron core and other accessories of the transformer are in the electric field around the winding. If not grounded, the core and other accessories will inevitably induce a certain voltage. Under the effect of the applied voltage, when the induced voltage exceeds the discharge voltage to ground. When it occurs, it will produce a discharge phenomenon. To avoid internal discharge of the transformer, ground the core.
