KDHG-220P Variable frequency transformer tester

وصف

Variable frequency transformer tester

الميزة الرئيسية
Only a simple digital setting is required: set the rated parameters of the transformer. The instrument will automatically record the data of the whole process, and automatically calculate and display the ratio polarity, volt-ampere characteristic curve, إلخ., eliminating the tedious labor of line change, manual voltage regulation, manual recording, sorting, and curve description.

No standard current transformer, current riser, load box, voltage regulating control box and large current conductor are required for on-site verification of current transformer. Simple test connection and operation are used to realize the verification of current transformer, which reduces the work intensity and improves the work efficiency, and facilitates on-site verification of transformer. Fast, simple, accurate and convenient.

Fully functional
It not only meets the test requirements of various types of CT (such as protection, القياس, TP) excitation characteristics (إنه, voltammetry characteristics), نسبة, polarity, secondary winding resistance, secondary load, ratio difference and Angle difference, but also can be used for various types of PT electromagnetic unit excitation characteristics, نسبة, polarity and secondary winding resistance test.

CT parameters such as inflection point voltage/current, 10%(5%) error curve, accuracy limit coefficient (ALF), instrument security coefficient (خ.س), secondary time constant (Ts), remanence coefficient (Kr), saturation and unsaturated inductance are automatically given.

The test meets GB1208 (IEC60044-1), GB16847(IEC60044-6), GB1207 and other transformer standards, and automatically selects which standard to test according to the type and level of transformer.

Based on the test principle of low frequency method, it can deal with the CT test with inflection point up to 40KV or more.

The test is simple and convenient, one key to complete the CT direct resistance, excitation, ratio and polarity test, and in addition to the load test, the other tests of CT are the same wiring mode.

10-inch color large screen Chinese graphical interface:
