What is Earthing Transformer or Grounding Transformer

WebTransient Earth Voltages (TEVs) are induced voltage spikes on the surface of the surrounding metalwork. TEVs were first discovered in 1974 by Dr John Reeves [3] of EA Technology. TEVs occur because the partial discharge creates current spikes in the conductor and hence also in the earthed metal surrounding the conductor.
