5. Performance characteristics
ISOTEST
®
test equipment excel with the following features:
Maximum safety of personnel by fiber optic controlled safety button
and ground connection monitoring
Significantly reduced hazards for personnel by pulse-shaped test
voltage and processor-controlled, load-dependent supply voltage
regulation
The processor-controlled, load-dependent supply voltage regulation
guarantees a constant test voltage even under worst-case load
conditions
The test voltage is adjusted using a self-calibrating spherical spark
gap according to VDE 0433 or an electronic spark gap
The high pulse repetition frequency allows testing speeds of up to
300 mm/s
By making use of extremely short, unipolar high-voltage pulses and a
specially designed evaluation circuitry, even the smallest pinholes
(channels) and voids can be detected and indicated with only a
minimum of material stress
Residual electrostatic charge on the test object is negligible if the
tests are performed correctly
Pinhole and leakage tests of non-conducting or semiconducting
materials
Testing of completely coated test objects by making use of capacitive
grounding
All
ISOTEST
®
test equipment carries the CE label and meets the
requirements of all relevant standards and specifications
(DIN EN/ISO, DVGW, etc.)
