CT Test Set (30 KA)
Get Price Quote
The CT Test Set (30 KA) can conduct on-site bus-type generator and current transformer testing, which are rated at 10-50kA. The indirect CT testing determines ratio and angle errors by comparing one test point. The other test point errors are tallied from CT running idle voltage-current curve with an open primary winding. The CT Test Set (30 KA) includes CT Test Set 5kA and CT VCC Converter. Steps : Determining ratio and angle error of the instrument-class current transformer (ICT) under test according to a standard test pro¬cedure, e.g. at a 20% of nominal current value. Constructing a Voltage-Current curve for ICT-under-test secondary winding throughout the whole current operating range from 01 to 120%. Determining the values of ICT errors from the Voltage-Current characteristics with consideration for the systematic error introduced into the ICT errors by transformer core material.

C.T. testing set is meant for determination of PHASE ANGLE ERROR AND RATIO ERROR OF Current transformer having secondary rated for 5 Amps. or 1 Amp. which are intended to be used on 50 Hz. The measurement is on principle of comparison and null indication on magnetic balance bridge. The basic unit is sensitive magnetic comparator and also it incorporates electronic null detector to facilitate the balance. The reference Current 5A. or IA. obtained from Standard Current Transformer and in comparison to that the vector length and phase displacement is measured. The ratio error in percentage and phase displacement in minutes are directly compared and indicated on dials.

The Megger MRCT is a light weight, robust, portable unit used to perform demagnetization, ratio, saturation, winding resistance, polarity, phase deviation, and insulation tests on current transformers. The MRCT automatically calculates ratio errors, saturation curves, and knee points. It provides a microprocessor-controlled variable voltage and current output and precision instrumentation for automatically testing single and multi ratio CTs, reducing testing time and increasing productivity. It directly connect to multi ratio CT and perform all tests-saturation, ratio and polarity, winding resistance and insulation-on all taps with the push of a button and without changing leads. It can be controlled via Megger´s Smart Touch View Interface (STVI) controller.
