Product Description

GDVA-405 0.02% Accuracy Portable Transformer CT PT Tester Current Transformer Test Equipment

Gdva-405 0.02% Accuracy Portable Transformer CT PT Tester Current Transformer Test Equipment
Current/voltage transformers can change high voltage into low voltage and large current into small current for measurement or protection system. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard small current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. change. At the same time, the transformer can also be used to isolate the high voltage system to ensure the safety of people and equipment.
