Übersetzung für "Dielectric test" in Deutsch

The dielectric test data of the coated copper foil are contained in Table 7.

Is the dielectric strength test with 1500 V AC permitted to be used for emergency luminaires?

Can a dielectric strength test at 1500 V AC be used for emergency luminaires?

To avoid damaging electronic operating devices, we urgently recommend that this dielectric strength test should not be performed.

After evaporation of the solvent, the foil is heated for 1 hour at 130°, 4 hours at 180° and 3 hours at 210° C., a firmly adhering polyamide/polyimide film being formed, the dielectric test data of which are contained in Table 7.

After the dielectric strength test has been satisfactorily carried out, but before any other test, the meters shall be supplied with electricity for at least half an hour at the reference voltage and with a current of about 01 lb, at unity power factor.

The test cell used of the three-electrode structure in line with the international standard IEC, with electrode spacing 2mm, can eliminate the effects of the stray capacitance and leakage on dielectric loss test results.

However, such tests in the insulation resistance test, dielectric loss tangent test, leakage current test due to lower test voltage and found that the sensitivity of the defect still needs to be improved.

A alternating current is applied with constant 1000 V for 20 seconds to test dielectric breakdown of the test sample.

For the dielectric voltage withstand test for the insulating boots and the insulating gloves, the testing cycle is half year, no puncture is allowed during the teat, and meanwhile the leakage current of the insulating boots shall not be over the limit value.

The dielectric breakdown test serves as an indicator to the presence of contaminating agents such as water, dirt, moist cellulosic fibers, and conducting particles in the insulating liquid.

As an alternative to measuring the insulation resistance, IEC60598-1 AnnexQ describes a dielectric strength test at 1500VAC (or 1.414 x 1500VDC).

To avoid damaging the electronic operating devices a dielectric strength test at 1500VAC must not be carried out.

The solution is applied to the rough side of a 35 ?m thick copper foil with the aid of a doctor blade (gap width 500 ?m), and the foil, in a horizontal position, is heated in a circulating air drying cabinet for 1 hour at 130°, for 2 hours at 180°, for 3 hours at 210° and for 3 hours at 240° C. In this way, uniform polyamide/polyimide film is formed which firmly adheres to the copper and the dielectric test data of which are given in Table 7.

We also called hipot testing, dielectric testing.

The manufacturer's instructions must indicate, in particular, the exclusive use for which these PPE types are intended and the nature and frequency of the dielectric tests to which they are to be subjected during their useful life.

Here, the customer can count on equipment such as laser aligners, instruments for measuring and analyzing vibrations and for balacing rotating objects, a digital wattmeter for determining the electrical parameters of the machine and for harmonic analysis, equipment for measuring the electrical isolation and polarization index of the machines, a high-voltage DC generator for dielectric tests, an instrument for measuring the electrical resistance of windings..in short, everything that's needed for assuring the quality of any job the company carries out.

The withstand voltage required in dielectric tests is roughly 5-10 times greater than the voltage which is present in the limiting case, and which corresponds approximately to the rated voltage of the power supply system.

For the specially aimed-at high-voltage applications, plastic sheets having a dielectric strength of at least 1.05 kV proved to be particularly efficient in dielectric strength tests of such sheets.
