1.The summary
YJJ series computer is a test device for testing the dielectric strength of insulating oil , which is
produced according to the National standard GB-86 (Determination Method For Dielectric
Strength of Transformer Oil). The values are preset with the adjusting switch and then the
device strictly works on the basis of the preset values. After doing one test, the results can be
printed automatically.
