Power Transformer Protection - ABB2018-5-9 · ABB Relays Power transformer protection 3. FAUL T CURRENTS It can also be seen that the primary current for aground fault between O .40% from the neutral is below 1,5 x In. Therefore in this case an overcurrent relay on the primary side can not detect ground faults located O -40%
Current transformer testing - Megger need for a comprehensive current transformer testing regime is evident when the alternative is considered: a catastrophically damaging current transformer fault. A fault leading to an open secondary could cause the primary current to overwhelm the insulation, causing the winding to short circuit.
