LOW TENSION TO MEDIUM VOLTAGE RESIN CAST CT/PT

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 mainfeeder CTs and thus protect the meters connected tothese bylimiting the current flowing through the meters.

SUMMATION CTs (RESINCAST)

• Current transformers intedned to summate the currents in a number of feeders in association with the feeder CTs is called summation Transformer.The performance I testing of these CTs are governed by IS-6949-1973,BS-3938,IEC-185.

BUSHING CTs (FIBREGLASS TAPED)

• Widely used byTransformer manufacturers for use inoil.
  PORTABLE CTs.
  Withclass 0.2 accuracy for metering & testingpurpose.

FURNACE CTs.

• CTs.WITHABS CASINGAND WITH SEALING ARRANGEMENTS:­
  Widely used by Electricity Board alongwith Energy meters.

LOW TENSION POTENTIALTRANSFORMER (TAPEWOUND I RESINCAST )

• These are offered in various ratios from 1100/11OV to 50 f 75V to suit the exact applications of the clients. Rated burdens upto 100 VA with accuracy classes of 1 or 0.5 can be offered.Various other types of low tensioninstruments transformers are also manufactured by usto suilthe exact requirements of our clients. Our team of specialised Engineers will be pleased to beof
  assistance to the clients in proper selection of instruments transformers for their applications.

PROTECTIONAND CLASS PS (CLASSX ) CTs, BOTH INTAPEWOUND I RESINCAST :
