Dielectric properties test

Dielectric properties tests define the capacity of a product to maintain the integrity of its insulation over a set time when subjected to electromagnetic forces of different types. This capacity is defined in the Basic Standards of Safety IEC 60664-1 and IEC 61140.

Tests:

Supported pulse voltage

This test determines the capacity of the insulation of a product against electrical shock defined by a specified peak, form and polarity over a set time

Test methods

The test methodology established at CEIS permits voltage lengths with wave form of 1.2/50 µs with peak values up to 36 kV.

Voltage supported at industrial frequency. (Dielectric rigidity)

This test determines the capacity of the insulation of a product against sinusoidal electrical over-voltage at 50/60 Hz over a set period of time.

Test methods

The test methodology established at CEIS permits implementing voltages with senoidal waves with peak values up to 80 kV.

Insulation resistance

The objective of this test is to establish the opposition or difficulty afforded by the insulation of an electrical product to direct current passing through it. This test is particularly appropriate to detect accelerated ageing, the cause and any actions to correct such.

Test methods

The test voltage may vary from 500 V to 1 kV direct current.
