Oil Insulation Tank Type AC Test Transformer Set for Inductive Voltage Transformers
Introduction
YDBW series tank type AC test transformers are situated in an enclosed and earthed metal tank, filled with transformer oil inside. Compare to cylinder type transformers, their capacity are bigger, can output larger test current. And these transformers can be optionally equipped with suitable bushing, multi output taps are available.
They are qualified for continuous duty, long duration tests, can be used for high voltage pollution tests, test line and capacity required continuous test.
This design is most suitable for using outdoor, and therefore is recommended to use in areas with poor climatic conditions, especially in high humidity areas and tropical countries.

Application
AC test transformer systems are conventional AC high voltage test equipments, mainly designed for medium capacitance testing objects, particularly for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests).
Especially when the load is inductive (like inductive voltage transformers), tests need resistive current, AC test transformer systems are the only choice.
Principle
Test transformer steps up the voltage coming from the regulating transformer. The controls act on the regulating transformer to adjust precisely the input voltage of the transformer and thus the test voltage.
If needed, a compensating reactor can be connected between the regulating and the test transformers and compensates the capacitive power required for the test object. This way, the regulating transformer and power line filter ratings can be kept small, and the requirements for the power supply are reduced.
