Page 6: Section 1
Section 1 Introduction and Safety An Introduction to Dielectric Withstand Testing with the HT-S The continuity test/dielectric withstand test is a production line test which is recognized by safety agencies worldwide as a valid criterion of safe assembly of end-use equipment. The test ensures that the primary circuit power and ground conductors were properly wired and connected for safe operation. -
Page 7: Test Personnel
Test Personnel Personnel require special training to conduct the dielectric withstand test. They should understand electrical fundamentals clearly, and be aware that high voltage is adept and creative at completing a path to ground. Instructions should include a warning against any metal jewelry. Operators should not allow others in the testing area, especially when tests are being conducted. -
Page 8: Safety Markings
The HT-S has been designed for one-touch operation with the right hand. If possible, it should be set up to the left and in front of the equipment under test. The equipment under test should be connected to the HT-S and then left alone by the operator. After the operator is clear of the Tester and the equipment under test, he should press the RESET Button, then the TEST button, with his right hand. -
Page 9: Using The Ht-S Dielectric Withstand Tester
Using the HT-S Dielectric Withstand Tester The dielectric withstand test involves high voltage and caution should be exercised when using the tester. The return lead of the tester is connected to ground potential and when properly connected to the equipment being tested, it will guard against the operator contacting high voltage. Always make sure the return lead is firmly connected to exposed dead metal before start testing. -
Page 10: Leakage Test
Leakage Test The HT-S leakage test uses a low-frequency circuit to check for excessive leakage between primary power components and ground. There is not a specific leakage current level pass/fail requirement at this time for most equipment, however, higher than normal leakage current on a particular part may indicate an assembly or component problem in the primary circuit. -
