Specifies the nominal characteristics of the isolating transformers used in airfield ground lighting for 6,6 A series circuits that are supplied by Constant Current Regulators up to 30 kW in rating. The isolating transformer gives electrical insulation, between the primary circuit that is supplied by a constant current regulator and the secondary connected to the load (generally the lamp of the luminaire) under the specified conditions.
