Product Description

The KDHG-518C variable frequency transformer characteristic tester only needs simple digital settings: set the rated parameters of the transformer. The instrument will automatically record data throughout the process, and automatically calculate and display the ratio polarity, volt-ampere characteristic curve, etc., eliminating the tedious work of changing lines, manual voltage adjustment, manual recording, sorting, and drawing curves.

 

It not only meets the test requirements of excitation characteristics (i.e. volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary load, ratio difference, and angle difference of various CTs (such as: protection, metering, TP), but also can be used for excitation characteristics, ratio, polarity, and secondary winding resistance tests of various PT electromagnetic units.

 

On-site verification of current transformers does not require standard current transformers, current boosters, load boxes, voltage control boxes, and high-current wires. Simple test wiring and operation are used to realize the verification of current transformers, which reduces the work intensity and improves the work efficiency, and facilitates on-site verification of transformers; fast, simple, accurate, and convenient.
