Quanti GHILC GROUND BOND - HIGH VOLTAGE INSULATION RESISTANCE - LEAKAGE CURRENT Reliable, Rugged, Fast, Accurate, Intrinsically Safe & Easily Programmable Measurements GROUND BOND - G WHY? Ground bond test (also referred to as PE resistance test, ground continuity test) determines whether the safety ground circuit of the Device Under Test (DUT) can adequately handle fault current if the product should ever become defective. The measured resistance has to be lower than the indicated limit from the applicable international standards. Usual values are << 500mΩ. GROUND BOND FUNCTION SPECIFICATIONS Quanti’s ground bond is a high current continuity test. Ground continuity is important for instance in manufacturing to ensure that the products leaving to the customers are safely grounded. OUTPUT CURRENT RANGE 3 - 30A AC With Quanti’s ground bond test you will test with the currents that most common standards require. User programmable output current from 3A to 30A AC provides extensive coverage for testing according to UL, IEC, EN and other requirements. OUTPUT CURRENT RESOLUTION 0.01A Adjustable output current and milliohm trip ranges to meet all safety specifications for ground bond test requirements. PROGRAMMABLE HIGH AND LOW RESISTANCE LIMITS A resistance measurement range from 0.5mΩ to 500mΩ, in conjunction with user-programmable high and low resistance limits with Pass/Fail indication, makes this tester ideal for production testing. 4 WIRE MEASUREMENT, CONSTANTLY ACCURATE RESULTS 4 wire measurement ensures accurate and repeatable measurements. When measuring low values resistances, an important error source can be found in the contact resistance. In many applications, the contact resistance value can go beyond the value which has to be measured. To cancel this error source a 4 wire measurement is used. For instance during the day the factory ambient temperature can change, which would mean wrong resistance values with 2 wire measurements if the error is not manually and constantly offset. DIELECTRIC WITHSTAND - H WHY? Hipot test or also called a Dielectric Withstand test verifies that the insulation of a product or component is sufficient to protect the operator from electrical shock. In a typical Hipot test high voltage is applied between a product’s current carrying conductors and for instance its metallic chassis. Hipot equipment measure extremely low currents like from microamps to milliamps. DIELECTRIC WITHSTAND (HIPOT) FUNCTION SPECIFICATIONS MAXIMUM OUTPUT CURRENT MAX TEST APPARENT POWER MEASUREMENTS 1) Except with some combination with other functions ENSURING CONNECTIVITY For optimum quality process control the connectivity to the DUT has to be ensured. Quanti gives the user several options to check this. The user can select either automatic or manual mode connectivity check. The parameters can be adjusted in order to meet high quality control standards and optimum yield. 1, 2 AND 4 CHANNEL SIMULTANEOUS MEASUREMENT POSSIBLE ARC DETECTION Arc is electrical spark occurred by voltage or current quickly changing. There should be no “sparking” in a Hipot test. Arc detection can help you to solve product quality issues. MINIMUM TEST CYCLE 1,2 SEC Exceptional high speed (see the diagram) allows to build ultra high speed high volume production test lines. This diagram shows how fast the test cycle can be. With minimum test time of 1sec the overall test cycle time is 1.18sec only. And this for all channels. TOTAL AND REAL CURRENT MEASUREMENTS Real Current measurement allows operators to monitor total and real current on a single screen. When testing highly capacitive devices, it is often desirable to make a distinction between real and total current. Total current is the vector sum of resistive and capacitive leakage current (see picture on the right). If the tester monitors only the total current, a substantial change in real current can often go undetected. The ability to separate the real and capacitive currents is an important requirement for AC Hipot testing. Nowadays some test requirements clearly specify the measurement of real rather than total current. DANGER: HIGH VOLTAGE INTRINSICALLY SAFE - FLOATING OUTPUT A floating electrical circuit is created by separating grounds; one for the operator, one for the equipment. This method creates an intrinsically safe operator environment. (please see the picture on the right). QUANTI HV-OUTPUT INSULATION RESISTANCE - I WHY? Insulation resistance test is one of the tests that are required by the electrical safety testing standards. The test measures insulation resistance of a Device Under Test, while phase and neutral are short circuited together. INSULATION RESISTANCE FUNCTION SPECIFICATIONS RESISTANCE MEASUREMENT MΩ MΩ 0.001 0.01 0.1 1 0.500 - 9.999 1.00 - 99.99 10.0 - 999.9 100 - 50 000 Accuracy: ± 5% to ± 15% depending upon the voltage and the selected range 50 - 499V DC: 0.5MΩ - 999.9MΩ, ± (5% of reading +2 counts) 1000MΩ - 9999MΩ, ± (8% of reading +2 counts) 10000MΩ - 50000MΩ, ± (17% of reading +2 counts) 500 - 1000V DC: 0.5MΩ - 999.9MΩ, ± (3% of reading +2 counts) 1000MΩ - 9999MΩ, ± (6% of reading +2 counts) 10000MΩ - 50000MΩ, ± (15% of reading +2 counts) MΩ) ENSURING CONNECTIVITY For optimum quality process control the connectivity to the DUT has to be ensured. Quanti gives the user several options to check this. The user can select either automatic or manual mode connectivity check. The parameters can be adjusted in order to meet high quality control standards and optimum yield. OUTPUT VOLTAGE 50 - 1000V DC Quanti measures insulation resistance in electrical systems and equipment such as: electrical machines, household appliances, transformers, cables, power supplies and so on. Measuring range is from 0.5MΩ to 50GΩ. VOLTAGE RESOLUTION 1V VOLTAGE ACCURACY ±0.5% OF RANGE RESISTANCE MEASUREMENT ACCURACY ± 5% TO ± 15% RAMP TIMER The voltage is ramped up from zero to the final value. Once the voltage reaches the selected value, it is kept at that value for a brief period (typically up to 5 seconds) before the resistance value is measured. LEAKAGE CURRENT - LC WHY? There are mainly two types of LC measuring methods: Touch Current (TC) and Protective Conductor Current (PCC). Touch Current is the current that flows when a human body touches the equipment. Protective Conductor Current is the current that flows from the unit through the grounding conductor into a household ground. LC is capable of performing tests that comply with standards for a wide range of equipment. LEAKAGE CURRENT FUNCTION SPECIFICATIONS DUT INPUT POWER CAPACITY 300 VAC / 16A MAX. SUPPORTS ALL TOUCH CURRENT AND PROTECTIVE CONDUCTOR CURRENT (EARTH LEAKAGE CURRENT) TESTS. Quanti Leakage Current test is designed to perform leakage current (touch current and protective conductor current) tests on general electric equipment (medical option on request). It enables you to conduct tests that conform the requirements of the applicable IEC, UL, EN and other standards. POWER SUPPLY SEPARATION The power supply for the Quanti Leakage Current is separate from the line power supply of the equipment that is being tested, preventing this way any damage to equipment due to wrong supply voltage being in the input.
