ASTM D D Electrical Test Set / Insulation Oil Dielectric Strength Tester

The breakdown test uses ac voltage in the power-frequency range from 45 to 65 Hz. I’m Online Chat Now. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. All the human interaction operations complete by the rotating mouse. The breakdown test uses ac voltage in the power-frequency range r877 45 to 65 Hz.

I was wstm up your machine one week ago. These liquids include petroleum oils, hydrocarbons, aetm askarels PCB used as insulating and cooling liquids in transformers, cables, and similar apparatus. How do you ship the products? Textile Testing Equipment There are seldom suppliers willing to do small spare parts for us, while YUYANG spends time with us, only for three burners, we appreciate them.

About Us About Us. Test Method D is not sensitive to low levels of these contaminants. This insulation oil breakdown voltage test set is multi-functional, stable, and easy for operation. Furniture Testing Machine Historical Version s – view previous versions of standard.

We appreciated for your company’s kind support on our projects. Test Method D should be used to determine the asm voltage of filtered and degassed liquids.

Dielectric Breakdown Voltage

These may include samples taken from circuit breakers, load tap changers, and other liquids heavily contaminated with insoluble particulate material. Electrical Test Set A low result in this test method indicates the presence of significant concentrations of one or more of these contaminants in the liquid tested. Oxygen Index Apparatus We have received all the instruments, and will test them, for the moment we have c877 good feelings.

Link to Active This link will always route to the current Active version of the standard. The voltage stress distribution between the parallel disk electrodes used in this test method are quasi-uniform and there is substantial stress concentration at the sharp edges of the flat disk faces.

The use of Procedure B will result in a more accurate value of breakdown voltage when testing such liquids.
