20、ssories must be returned at least once a year to an Associated Research authorized service center for calibration and inspection of safety related components. Associated Research will not be held liable for injuries suffered if the instrument is not returned for its annual safety check and maintaine

Associated Research will not be responsible for any injuries sustained due to unauthorized equipment modifications or use of parts not specified by Associated Research. Instruments returned to Associated Research

22、 with unsafe modifications will be returned to their original operating condition at your expense. TEST STATION Location Select an area away from the main stream of activity which employees do not walk through in performing their normal duties. If this is not practical because of production line flo

23、w, then the area should be roped off and marked for HIGH VOLTAGE TESTING. No employees other than the test operators should be allowed inside. SAFETY 4 If benches are placed back-to-back, be especially careful about the use of the bench opposite the test station. Signs should be posted: DANGER - HIG

24、H VOLTAGE TEST IN PROGRESS - UNAUTHORIZED PERSONNEL KEEP AWAY. Power Dielectric Voltage-Withstand Test Equipment must be connected to a good ground. Be certain that the power wiring to the test bench is properly polarized and that the proper low resistance bonding to ground is in place. Power to the

25、 test station should be arranged so that it can be shut off by one prominently marked switch located at the entrance to the test area. In the event of an emergency, anyone can cut off the power before entering the test area to offer assistance. Work Area Perform the tests on a nonconducting table or

26、 workbench, if possible. There should not be any metal in the work area between the operator and the location where products being tested will be positioned. Position the tester so the operator does not have to reach over the product under test to activate or adjust the tester. If the product or com

27、ponent being tested is small, it may be possible to construct guards or an enclosure, made of a non-conducting material such as clear acrylic, such that the item being tested is within the guards or enclosure during the test, and fit them with switches so that the tester will not operate unless the

28、guards are in place or the enclosure closed. Keep the area clean and uncluttered. All test equipment and test leads not absolutely necessary for the test should be removed from the test bench and put away. It should be clear to both the operator and to any observers which product is being tested, an

29、d which ones are waiting to be tested or have already been tested. Do not perform Hipot tests in a combustible atmosphere or in any area where combustible materials are present. TEST OPERATOR Qualifications This instrument generates voltages and currents which can cause harmful or fatal electric sho

30、ck 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. Safety Procedures Operators should be thoroughly trained to follow these and all other applicable safety rules and procedures before th

31、ey begin a test. Defeating any safety system should be treated as a serious offense and should result in severe penalties, such as removal from SAFETY 5 the Hipot testing job. Allowing unauthorized personnel in the area during a test should also be dealt with as a serious offense. Dress Operators sh

32、ould not wear jewelry which could accidentally complete a circuit. Medical Restrictions This instrument should not be operated by personnel with heart ailments or devices such as pacemakers. TEST PROCEDURES !NEVER PERFORM A HIPOT TEST ON ENERGIZED CIRCUITRY OR EQUIPMENT! If the instrument has an ext

33、ernal safety ground connection be sure that this is connected. Then Connect the return lead first for any test regardless of whether the item under test is a sample of insulating material tested with electrodes, a component tested with the high voltage test lead, or a cord-connected device with a tw

34、o or three prong plug. Plug in the high voltage test lead only when it is being used. Handle its clip only by the insulator-never touch the clip directly. Be certain that the operator has control over any remote test switches connected to the Hipot. Double check the return and high voltage connectio

35、ns to be certain that they are proper and secure. 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 te

36、st fixtures-before handling it or disconnecting the test leads. HOT STICK probes can be used to discharge any capacitance in the item under test as a further safety precaution. A hot stick is a nonconducting rod about two feet long with a metal probe at the end which is connected to a wire. To disch

37、arge the device under test, two hot sticks are required. First connect both probe wires to a good earth ground. Then touch one probe tip to the same place the return lead was connected. While holding the first probe in place, touch the second probe tip to the same place where the high voltage lead w

38、as connected. KEY SAFETY POINTS TO REMEMBER: Keep unqualified and unauthorized personnel away from the test area. Arrange the test station in a safe and orderly manner. Never touch the product or connections during a test. In case of any problem, turn off the high voltage first. Properly discharge a

39、ny item tested with DC before touching connections. WARNING INTRODUCTION 6 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 failu

40、re of insulation to effectively prevent the flow of current, sometimes evident by arcing. If voltage is gradually raised, breakdown will begin suddenly at a certain voltage level. Current flow is not directly proportional to voltage. Once breakdown current has flown, especially for a period of time,

41、 a repeated application of voltage will often show breakdown beginning at a lower voltage than initially. Conductive: Having a volume resistivity of no more than 103 ohm-cm or a surface resistivity of no more than 105 ohms per square. Conductor: A solid or liquid material which has the ability to le

42、t current pass through it, and which has a volume resistivity of no more than 103 ohm-cm. Current: The movement of electrons through a conductor. Current is measured in amperes, milliamperes, microamperes, nanoamperes, or picoamperes. Symbol = I Dielectric: An insulating material which is positioned

43、 between two conductive materials in such a way that a charge or voltage may appear across the two conductive materials. Direct Current, DC: Current which flows in one direction only. The source of direct current is said to be polarized and has one terminal which is always at a higher potential than

44、 the other. Hipot Tester: Common term for dielectric-withstand test equipment. Hypot: Registered trademark of Associated Research, Inc., for its dielectric-withstand test equipment. Insulation: Gas, liquid or solid material which has a volume resistivity of at least 1012 ohm-cm and is used for the purpose of resisting current flow between conductors. Insulation Resistance Tester: An instrument or a function of an instrument capable of measuring resistances in excess of 200 megohms. Usually empl
