2 For this reason, it is necessary to confirm for what portion of what standard testing is to be performed when purchasing a hipot tester. Although the 500 VA capacity hipot testers available from KIKUSUI can basically be ap-plied to tests specified in all safety standards, we recommend that you consult with us prior to purchase in order to select the model that best matches your specific SERIESELECTRICAL SAFETY to to 292kgWD215W 66H 5000MW (DC25V 1000V) (6A 60A)11kgWD430W 88H to 325kgWD320W 88H 270 DmmTOS320030 A 30mA (RMS) to (3A 30A)9kgWD430W 88H ,34 GPIBRS-232 CTimerUSBRise TimeEquipped with rise time control functionFall TimeEquipped with fall time control functionGPIBE quipped with GPIB interface as standardRS-232 CEquipped with RS-232C interface as standardDimensionsDWeightWACWIRDCWE quipped with timer to 245kV/100mA(500VA)ACW15kgWD320W 132H ,265kV/100mA(500VA)

For a spe-cific definition of each term, refer to the relevant safety definitions of the terms indicated here are basically excerpts from the IEC 61010-1 2ndEdition.

Dielectric strength test is commonly used in the safety standards.

Current that is measured using a body impedance network (body model) that matches the body Conductor CurrentCurrent flowing through the protective earthing conductor under normal operating Impedance Network, Measurement NetworkCircuit network (body model) representing the human body impedance that is used in the measurement of the TC. There are differences in the body response types and safety standards. However, it is usually defined using resistors and ResponsesBody responses when a hazardous current flows. There are four types of responses: perception, reaction, let-go, and electric burn. (IEC 60990)BFour Principal Tests for Evaluating the Safety of Electrical and Electronic ProductsElectrical products consists of many parts.

8 Mostly, they are composed of electric parts thatconduct electricity (conductors) and those that block electricity (insulators). If the insulatorbetween parts that are accessible by humans and parts that are hazardous is defective, elec-tric shock may occur if a human being touches the electric equipment. If the defective insulat-ing part heats up, it may cause a fire. To prevent such accidents, evaluating the safety ofelectric equipment is extremely important. The typical tests are withstanding voltage test,insulation resistance test, leakage current test, and earth continuity test. Withstanding voltage and insulation resistance testsThese tests check whether the insulation performance of insulation section (solid insula-tion, clearance, etc.) between hazardous section and accessible section are sufficient.

9 Leakage current testThis test measures the amount of current that flows assuming the case in which a humanactually touches the electric equipment. Earth continuity testThis test checks whether the protective bonding is achieved by low resistance for equip-ment designed to use protective earthing for securing four tests are mandatory type tests that must be executed under the safety standardssuch as IEC and UL as well as the Electrical Appliance and Material Safety Law. The with-standing voltage and earth continuity tests that are performed between the primary circuit(parts connected to the commercial power line that may become an immediate threat) andaccessible locations are routine tests that must be performed on all products on a B-1 Safety evaluation testNLPEZ1Z2 EnclosureElectronic EquipmentSecondaryPrimaryMainsAccessible conductive partElectric shock occurs if the impedance of Z1 and Z2 is Principal Tests for Evaluating the Safety of Electrical and Electronic ProductsWithstanding Voltage TestThe withstanding voltage test evaluates whether the electric insulation section of an electricequipment or parts have sufficient dielectric strength for the working voltage.

10 It is also calleddielectric withstand test or hipot this test, a voltage stress that is much higher than the voltage that is normally applied tothe insulation section for a specific time to see whether a dielectric breakdown occurs. If acurrent flowing through the insulation section exceeds the limit during the test period, it isassumed that a dielectric breakdown occurred. If a dielectric breakdown does not occur, theinsulator is assumed to have sufficient dielectric principle of the withstanding voltage testFig. B-2 Withstanding voltage testAC test and DC testFor the test between the primary circuit and an accessible section as shown in Fig. B-2, anAC voltage is normally applied. If a filter for eliminating the electromagnetic interference ispresent in the location corresponding to Z1 or Z2 and its capacitive component is large, thedistinction between the current flowing through the filter and the current used to assume adielectric breakdown will be difficult.
