• The level of the busduct flanges from ground/rail level is indicated in the General Arrangement drawings of the transformer. The complete details of busduct flange is furnished by us giving complete dimensional details for the matching flanges, bolt spacing, bushing terminal details, etc. 4.9 MARSHALLING BOX • The transformer is provided with certain fittings directly mounted on the transformer at various locations. These fittings are having electrical contacts or terminals which are required to be connected to the protection schemes to give alarm/annunciation under abnormal conditions and if further required to disconnect the transformer form mains. To facilitate connections of all such devices to the protective scheme, the cable from all such contacts are wired up to a weather-proof terminal box, this box called marshalling box, is also used for housing Oil Temperature Indication (OTI) and winding Temperature Indicator (WTI). • The capillaries from OTI & WIT come out from the bottom of the Marshalling box through suitably recessed gland plate thus preventing ingress of dust. • It has a detachable gland plate with glands through which cables enter and leave. It has a rain shed provided on top to prevent rain falling directly over it. All these provisions make Marshalling Box a Weather-Proof enclosure. 4.10 ERECTION OF HV TURRETS AND BUSHINGS METHOD OF LIFTING CONDENSER BUSHING FROM PACKING CASE AND MOUNTING ON THE TRANSFORMER AT AN ANGLE TBI AF/IMS001/R3 Installation, Commissioning, Operation & Maintenance of Transformer 52 | P a g e • Before starting the erection work of Condenser Bushing, lift the Bushing from its crate and keep it vertical and check the oil level. Confirm that oil level is up to the centre of oil sight window of Bushing. • If oil is drained from the tank a continuous supply of dry air should be ensured while removing the blanking plates and fixing the bushing turrets and bushings.Dry air shall have a dew point of -40OC or better. • Total exposure time should not exceed 8 hrs. At the end of each day’s work, blank off all openings and pressurise with dry air. • If weather is bad (rain, snow or fog) the tank should not be opened unless adequate shelter is provided. • For details of connections from winding to the bushing please refer to the specific drawing and suppliers catalogue given in the instruction manual. • Ensure that a fresh gasket is used while mounting the bushing.Ensure that the air release pipe connections are oriented towards the correct directions. • Bushing shall be mounted in the order of B, A, C or B, C, A. • While mounting the bushings, ensure that the oil level gauge is oriented away from the transformer. • While lowering draw lead type condenser bushing the cable shall be held tightly by using strong steel/plastic rope. Remember that dropping of cable can cause injury to the personnel and damage to the transformer. • Check and ensure that secondary terminal of turret mounted C.T. if any are connected to the proper terminals on the terminal board. • Check and ensure that secondary leads of C.T's. mounted inside the transformer are connected to the proper terminals in the terminal board.
