  • Page 8: Safety

    SAFETY SAFETY PRECAUTIONS REQUIRED FOR HIGH VOLTAGE TESTING! GENERAL: This product and its related documentation must be reviewed for familiarization with safety markings and instructions before operation. This product is a Safety Class I instrument (provided with a protective earth terminal). Before applying power verify that the instrument is set to the correct line voltage (115 or 230) and the correct fuse is installed.
  • Page 9 The instrument and its power cord, test leads, and accessories must be returned at least once a year to a Slaughter Company authorized service center for calibration and inspection of safety related components. Slaughter Company will not be held liable for injuries suffered if the instrument is not returned for its annual safety check and maintained properly.
  • Page 10 If the instrument is used in a matter not specified by Slaughter Company, Inc. the protection provided by the instrument may be impaired.
  • Page 11 SAFETY TEST OPERATOR Qualifications This instrument generates voltages and currents which can cause harmful or fatal electric shock and must only be operated by a skilled worker trained in its use. The operator should understand the electrical fundamentals of voltage, current, and resistance.
  • Page 12 SAFETY WARNING NEVER TOUCH THE ITEM UNDER TEST OR ANYTHING CONNECTED TO IT WHILE HIGH VOLTAGE IS PRESENT DURING THE HIPOT TEST. 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.

  • Page 13: Glossary Of Terms

    INTRODUCTION GLOSSARY OF TERMS (as used in this manual) Alternating Current, AC: Current which reverses direction on a regular basis, commonly in the U.S.A. 60 times per second, in other countries 50 times per second. Breakdown: The failure of insulation to effectively prevent the flow of current, sometimes evident by arcing.
  • Page 14 INTRODUCTION Leakage: AC or DC current flow through insulation and over its surfaces, and AC current flow through a capacitance. Current flow is directly proportional to voltage. The insulation and/or capacitance is thought of as a constant impedance, unless breakdown occurs.

  • Page 15: Introduction

    INTRODUCTION INTRODUCTION The importance of testing..User safety In an era of soaring liability costs, original manufacturers of electrical and electronic products must make sure every item is as safe as possible. All products must be designed and built to prevent electric shock, even when users abuse the equipment or bypass built in safety features.
  • Page 16 INTRODUCTION If, during the time the component is tested, stray current flow remains within specified limits, the device is assumed safe under normal conditions. The basic product design and use of the insulating material will protect the user against electrical shock. The equipment used for this test, a dielectric-withstand tester, is often called a "hipot"...
  • Page 17 INTRODUCTION AC testing advantages AC testing is generally much more accepted by safety agencies than DC testing. The main reason for this is that most items being hipot tested will operate at AC voltages and AC hipot testing offers the advantage of stressing the insulation alternately in both polarities which more closely simulates stresses the product will see in real use.
  • Page 18 INTRODUCTION DC testing advantages Once the item under test is fully charged the only current flowing is true leakage current. This allows a DC hipot tester to clearly display only the true leakage of the product under test. The other advantage to DC testing is that since the charging current only needs to be applied momentarily the output power requirements of the DC hipot tester can typically be much less than what would be required in an AC tester to test the same product.
  • Page 19 INTRODUCTION may under certain conditions require an IR test on the product before a Hipot test is performed. This typically is not a production line test but a performance design test. The insulation resistance test is very similar to the hipot test. Instead of the go/no go indication that you get with a hipot test the IR test gives you an insulation value usually in Megohms.
