Measuring Insulation Resistance of Capacitors
How can a megohmmeter be used characterize a capacitor? The impedance parameters of a passive component are measured using an LCR meter. Not always so. The capacitor's dielectric material is subjected to DC resistance tests to measure its quality and subjected to high voltage tests to determine its breakdown. The QuadTech 1865 Megohmmeter/IR Tester is ideally suited to IR testing of capacitors.
Measuring Large Capacitors with the 1865-52 Component Test Fixture
Measuring the insulation resistance of capacitors with the 1865 Megohmmeter is possible using the 1865-52 Component test fixture. This test fixture has interchangeable modules for leaded devices, SMD devices plus 100kW and 1MW quieting resistors and associated cables. A safety interlock prevents the operation of the test fixture with the cover open.
Characteristic Cable Impedance (1600 Series)
Can the impedance of coaxial cable be accurately measured? The 1600 Series Digibridges can do it! Measuring the open circuit and short circuit impedance of the cable and substituting them into an equation will yield the cable's characteristic impedance.
Connection of Isolation Transformer to Safety Tester
IEC 60601-1 specifies the isolation of the mains supply from the circuit under test to determine the worst-case leakage current. How is this done in an earth leakage current test? This application note illustrates the connection of an isolation transformer to a G6100 Electrical Safety Analyzer.

QuadTech Partners with UL Knowledge Solutions
|
| |
|
QuadTech, Inc. and Underwriters Laboratories (UL) have entered into an agreement to jointly market UL's Knowledge Programs for the Medical Industry. The first co-sponsored seminar is 'Designing and Testing for Compliance to IEC 60601-1', a newly developed two day comprehensive study of IEC 60601-1.
|
| |
|
This technical seminar will be facilitated by experienced UL Engineers and encompasses the National Deviations for the U.S. (UL 60601-1), Canada (CAN/CSA C22.2 No. 601.1) and the European Union (EN 60601-1). Learn how to write design and purchase specifications for critical components, generate insulation diagrams and what worldwide certification entails.
|
| |
|
|
The 'Designing and Testing for Compliance to IEC 60601-1' Seminar costs $895 and will be offered in California in July and New Jersey in October 2003. A copy of the UL Standard and Seminar Proceedings are included in this price. Space is limited and will be filled on a first come, first serve basis. Register online or call Stephanie Lopez at 800-253-1230, ext 230.

1864 Megohmmeter - Simply Indestructible
Chances are that if you work on a flight line you've seen an 1864 Megohmmeter. This steel-cased Meg is a workhorse in many aerospace applications. Used to check insulation resistance on wire bundles on commercial aircraft fuel pumps and hydraulic pump motors, the portable 1864 never quits. This versatile megohmmeter has also been used to test the insulation resistance of ceramic, mica and paper capacitors. Measurements can be made up to 200TW with test voltages from 10-1090V DC. Ground and guard terminals permit measurement of grounded and ungrounded two- or three- terminal resitors. An excellent megohmmeter by any standard. |
