how much nh3 LeakSpy for transformers

In some transformers, the tank of the transformer is filled with a layer of nitrogen above the oil in which the windings and the core are immersed. Nitrogen, being an inert gas, reduces the risk of a fire hazard. It also protects the transformer oil and the transformer insulation from reacting with oxygen in the air and deteriorating.
