Product introduction

NRCTP-100P CT PT Analyzer is designed for analyzing current transformers (CT) and voltage transformers (PT) of protection or measurement use. Which is suitable for laboratory and on-site test. It’s a new generation of innovative CT, PT test equipment, which is based on the series of NRFA automatic instrument transformer tester, which already had a good reputation. This device uses high-performance DSP and ARM, with advanced manufacturing process to ensure stable and reliable performance, full-featured, high degree of automation, high efficiency test, it is the professional testing equipment of instrument transformer in the power industry.

Alternative name

Voltage characteristic tester, volt-ampere characteristic variable ratio polarity tester, voltage characteristic tester, transformer volt-ampere characteristics tester, transformer tester, transformer integrated tester

The Characteristics of the products

1. With full-function, it not only can test the excitation characteristics (also named VA rating curve), ratio, polarity, secondary winding resistance, secondary burden, phase or angle difference for all kinds of CT (such as protective type, measuring type and TP), but also can test the VA rating curve, ratio, polarity, secondary winding resistance, phase or angle difference for all kinds of PT.

2. Automatically given the knee point voltage/ current, 10% or 5% error curve, accuracy limit factor (ALF), instrument safety factor (FS), secondary time constant (Ts), remanence factor (Kr), saturated and unsaturated inductance and other parameters of CT and PT..

3. The test meet GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207 and other types of transformers standards, it can automatically select the suitable standards to test according to the type and level of transformer.

4. Based on an advanced low-frequency testing theory , the knee point voltage of CT can be up to 30KV

5. Beautiful and friendly interface.

6.The device can store 2000 groups of test data automatically even a sudden of brownout. For data analysis, U disk can transfer to PC after testing and produce WORD reports.

7.The test is simple and convenient, one key to complete the DC resistance, excitation, ratio and polarity test of CT, in addition to the load tests, CT various other tests are based on the same kind of wiring method.

8.Easy to carry, device weight less than 9.0 kg.
