Standard CT
6300A
The Model 2509 Instrument Current Transformer is a 6300 A ampere CT designed for precision measurement of AC current or for Instrument Current Transformer calibration applications. The CT can be installed on a bus bar or it can be used with a primary conductor consisting of number of turns. The 6300 CT is designed with a tapped primary & a tapped secondary winding, thus providing a large number of ratios over a range of 5 to 6300 amperes.

Compensating Reactor
The compensating reactors are accessories for the CTS-12KSA/ACTS-12K Capacitance & Tan Delta Test Set. The use of one or more compensating reactors increases the capacitance that the internal power supply can excite to conduct measurements. As the measuring range of the CTS-12KSA / ACTS 12K exceeds the kVA rating of the internal power supply, one way of using the test set over its entire measuring range is to form a resonant circuit with the test sample. The use of one or more compensating reactors forms partial resonating circuit with the test specimen, thereby reducing the power supply requirement.
