Surge Protection of Substations - INMR

Considerations in Substation ProtectionInsulation TypeAssets Requiring Surge ProtectionSurge Sources & Mitigation MethodsLightning Surges on Incoming LinesTypes of Substations & Special Protection ConsiderationsTypes of Arresters Used in SubstationsArrester Selection ConsiderationsConsiderations in the protection of substations are listed and covered below showing different performance criteria: Failure Rate This is the acceptable number of insulation failures over the service life of the station. A station is typically designed according to some quantifiable performance levels, as outlined in Section 3.4 of IEC 60071-2 and in IEEE 1313.2. Moreover, IEC 62305-2–2010 identifies tolerable risks for a substation, where risk level is affected by different types of service loss. Required Insulation Withstand Level (Urw) This is given in terms of surge types such as fast, very fast, slow and temporary overvoltages. Safety Margins The safety margins typically used in substations are 15% for transformer windings and 5% for air insulation. Separation Distance This is the distance between arrester and intended protected equipment. If too great, voltage at the protected equipment could exceed its required insulation level due to reflections and traveling waves. Open Bre...Get price
