1. Introduction 1.1 Safety Symbols 1.1.1 Product Marking Symbols Product will be marked with this symbol when it is necessary to refer to the operation and service manual in order to prevent injury or equipment damage. Product will be marked with this symbol when hazardous voltages may be present. Product will be marked with this symbol at connections that require earth grounding. -

1.2 Glossary of Terms Alternating Current, AC: Current that reverses direction on a regular basis, commonly in the U.S.A. 60 per second, in other countries 50 times per second. Breakdown: The failure of insulation to effectively prevent the flow of current sometimes evidenced by arcing. -
Page 9: Safety
The instrument, its power cord, test leads, and accessories must be returned at least once a year to EEC customer support department for calibration and inspection of safety related components. EEC will not be held liable for injuries suffered if the instrument is not properly maintained and safety checked annually. -

test station. Signs should be posted: "DANGER - HIGH VOLTAGE TEST IN PROGRESS - UNAUTHORIZED PERSONNEL KEEP AWAY." Work Area Perform the tests on a non-conducting table or workbench, if possible. If you cannot avoid using a conductive surface, be certain that it is connected to a good earth ground and the high voltage connection is insulated from the grounded surface. -

will flow through any available ground path. Rules Operators should be thoroughly trained to follow all of the aforementioned rules, in addition to any other applicable safety rules and procedures. Defeating any safety system should be considered a serious offense with severe penalties such as removal from the Hipot testing job. Allowing unauthorized personnel in the area during a test should also be dealt with as a serious offense. -
Page 12: Key Safety Points To Remember
When testing with DC, always discharge the capacitance of the item under test and anything the high voltage may have contacted--such as test fixtures--before handling it or disconnecting the test leads. HOT STICK probes can be used to discharge any capacitance in the device under test as a further safety precaution. -
Page 13: The Different Types Of Safety Tests
1.5 The Different Types of Safety Tests 1.5.1 Dielectric Withstand Test The principle behind a dielectric voltage - withstand test is simple. If a product will function when exposed to extremely adverse conditions, it can be assumed that the product will function in normal operating circumstances. - Page 14 Types of Failures only detectable with a Hipot test Weak Insulating Materials Pinholes in Insulation Inadequate Spacing of Components Pinched Insulation Dielectric Withstand Test; AC verses DC Please check with the Compliance Agency you are working with to see which of the two types of voltages you are authorized to use.
- Page 15 AC testing disadvantages One disadvantage of AC testing surfaces when testing capacitive products. Again, since AC cannot charge the item under test, reactive current is constantly flowing. In many cases, the reactive component of the current can be much greater than the real component due to actual leakage. This can make it very difficult to detect products that have excessively high leakage current.

concerning exactly what equivalent DC test voltage is appropriate. 1.5.2 Insulation Resistance Test Some "dielectric analyzers today come with a built in insulation resistance tester. Typically, the IR function provides test voltages from 500 to 1,000 volts DC and resistance ranges from kilohms to gigaohms. -
