Otherwise,when the tank is not equipped with any protection system,and if it is subjected to a similar low impedance fault,the tank is still exposed to very dangerous pressure levels (up to 15 bars,217 psi) after 120 ms (Figure 5.b) without the tank protection,the static pressure stabilizes around 7.5 bars (109 psi) and the transformer What are the requirements for oil containment in a transformer?What are the requirements for oil containment in a transformer?It defines the minimum requirements for transformer oil containment .All transformers and equipment containing oil volumes greater than 1,000 litres are required to be installed within a bund.Reference shall be made to SDI 532 - Plumbing and drainage for the drainage Transformer oil containment - Endeavour Energy What causes a transformer tank to go over 50kV?What causes a transformer tank to go over 50kV?Phase to phase and earth faults are virtually impossible.Lightning takes out a lot of pole transformers causing them to explode oil over an area greater than any bund could catch.Again,the root cause is now well understood.A lightning induced flash over on the HV bushing causes the transformer tank to rise to more than 50kV.Bunding Oil Filled Transformers To Bund or Not to Bund

Hydropneumatic tanks work best with an air cushion of ¼ to ½ the tank capacity.This cushion decreases as water absorbs air and the tank loses its ability to pressurize the system.To keep that from happening,there must be an automatic way to replenish the air volume.Adding air manually isLiquid Filled Transformer Applicationsvoltage VCB,or VFI internal to transformer tank Test circuit consisted of the source,medium voltage VCB,cable,hardened transformer, load bank The test sequence consisted of 1.Close VCB or VFI to energize the transformer 2.Apply a highly inductive light load consisting of a load bank on the transformer secondary 3.Liquid storage GuidelinesTake into consideration the capacity displaced by other tanks within the same bunded area and any foundations.Treat interconnected tanks as a single tank of equivalent total volume for the purposes of the bund design criteria.For flammable liquids,bund capacity should be at least 133% of the net capacity of the largest tank.If an automatic fire
