PRIMARY WINDING:-

• Primary winding is of braided electrolytic copper conductor with double cotton covering. Varnished fibreglass sleeve is provided as an additional insulation on this conductor. In case of live tank construction, the primary is wound on insulated secondary. The primary is positioned properly to sustain dynamic forces developed during short circuit condition. In case of Dead Tank construction, the primary is encapsulated in circular rigid fibre glass ring and aluminum pipe to form EYE BOLT construction

INSULATION:-

• High quality crepe insulating paper is used to build up main insulation of the CT. In live tank design, insulation is built up on secondary core and secondary leads are brought out through a metallic galvanised pipe. In Dead Tank CT primary Winding is encapsulated in fibre glass ring and Aluminum pipe.
• Main insulation is built up on primary winding (Paper condenser is formed on the pipe) with fine grading of insulation. Semiconducting shield is used togive linear distribution of Electric stress along the length of the bushing the paper insulation is dried in oven under very high vacuum and strictly controlled conditions. Filtered and de-aerated EHV Grade oil is filled in CT while CT is under vacuum. To seal it, the space left for expansion on the top is filled with dry and pure nitrogen through non-returanable valve at pre-determined pressure.

RANGE OF MANUFACTURE:-

• Tapewound ring type current Transformers with and without mounting arrangements.
• Tapewound ring type CTs with sealing arrangements.
• Tapewound wound primary CTs (WPL)
• Resincast (epoxy) BPL CTs.
• Resincast (epoxy) wound primary (WPL) CTs.
• Bushing CTs (Fibreglass taped).

CORE BALANCE CTs (Resincast):-

• These are used in detecting earth faults of very small magnitude. A three phase cable is passed through these CTs & the unbalanced currents in the three phases set up a differential flux giving rise to a current on the secondary side of these CTs sufficient to actuate a relay.

INTERPOSING CURRENT TRANSFORMERS (Resincast):-

• Used in matching the ratios of main feeder CTs for differential protection schemes. These also find application as saturable CTs used in conjunction with main feeder CTs and thus protect the meters connected to these by limiting the current flowing through the meters.
