Breakdown Voltage Tester TOR-100 (TOR-100 SL)
DESCRIPTION
TOR-100 tester is designed to determine the electrical breakdown voltage of transformer oil and other liquid dielectrics in accordance with IEC 60156, VDE 0370, ASTM D877, ASTM D1816, IRAM 2341. This list of standards may be supplemented and modified both with customer preferences taken into consideration and as new versions of standards become available.
Principle of operation
The working core of the tester is a high-voltage transformer and electronic modules. The principle of operation of the device is to gradually increase the voltage on the secondary winding of a high-voltage transformer from zero to maximum value, or to a value at which there will occur a breakdown of a liquid dielectric poured into a measuring cell installed on the high-voltage contacts of the transformer and constituting a part of its output electrodes.
A voltage rise at the high-voltage contacts of the secondary winding of the transformer occurs due to a gradual increase in the voltage on the primary winding when sinusoidal voltage is applied thereto from a controlled master inverter.
