As per ASTM D 149 and IEC 60243, manufacturers need to test solid insulating material for dielectric breakdown voltage. This checking of strength of solid insulating materials is done as per the utility's frequency. We have a series of High Voltage Testers right from 50kV to 150kV to carry out this dielectric strength test (Hipot)
The source is designed for the capacity as mentioned in clause 6. The equipment provides an electronic circuit for current sensing & tripping. Various tripping current ranges are provided to protect the sample as well as the equipment. The high potential test system is designed for all the methods of voltage applications (voltage profiles) such as short time test, step by step test, slow rate of rise test etc. - thus it caters to requirements of the ASTM D 149 test standard.
Likewise, Short-time (rapid-rise) test, 20 s step-by-step test, Slow rate-of-rise test, 60 s step-by-step test, Very slow rate-of-rise test and Proof tests can be performed in accordance with IEC 60243.
We provide an oil bath environment (test chamber) with various electrodes as mentioned in the Table 1 (page 3) of the standard. We welcome inquiries for customised high voltage testers with customised electrode dimensions.
In the PC based models, voltage, time, rate of rise & all other parameters can be set. The voltage against time graphs (real-time as well as test results) can be seen in the software. User can generate reports, export to MS Office / PDF, save & set all parameters.
