|
The PROFITEST INTRO provides professional electricians with a universal, compact and rugged, state-of-the-art measuring tool. The test instrument is capable of executing all measurements for testing the effectiveness of safety measures in electrical systems as required by IEC 60364-6 (DIN VDE 0100-600) and other country specific standards, and as specified in the individual sections of DIN EN 61557 (VDE 0413). Thanks to its intelligent and ergonomic design, intuitive operation and an advanced technical concept, it’s aligned consistently to routine daily tasks making it the ideal companion for any electrician.
Large Voltage and Frequency Ranges
A broad-range measuring device permits use of the test instrument in all alternating and 3-phase electrical systems with voltages from 65 to 500 V and frequencies of 16 to 400 Hz.
Loop and Line Impedance Measurement
Measurement of loop and line impedance can be performed in the 65 to 500 V range. Conversion to short-circuit current is based on the respective nominal line voltage, insofar as the measured line voltage is within the specified range. Measuring error for the PROFITEST INTRO is also taken into account for conversion. Outside of this range, short-circuit current is calculated on the basis of momentary line voltage and measured impedance.
Measurement of Insulation Resistance Using Nominal Voltage with Variable or Rising Test Voltage
Insulation resistance is usually measured with a nominal voltage of 500, 250 or 100 V. A test voltage which deviates from nominal voltage, and lies within a range of 20/50 to 1000 V, can be selected for measurements at sensitive components, as well as systems with voltage limiting devices. Measurement can be performed with a constantly rising test voltage in order to detect weak points in the insulation and determine tripping voltage for voltage limiting devices. Voltage at the device under test and any triggering/breakdown voltage appear at the test instrument’s display.
Low-Resistance Measurement
Bonding conductor resistance and protective conductor resistance can be measured with a test current of ≥ 200 mA DC, automatic polarity reversal of the test voltage and selectable current flow direction. If the adjustable limit value is exceeded, an LED lights up.
Testing of Residual Current Devices (RCCBs)
- Testing of equipment and RCCBs with rising residual current including indication of tripping current and contact voltage
- Testing for N-PE reversal
- Testing of RCCBs with the following nominal currents: ½ • IΔN, 1 • IΔN, 2 • IΔN, (5 • IΔN up to 100 mA)
- Selective , SRCDs, PRCDs (Schukomat, Sidos and others), types G/R, AC, A and F; types B, B+ and EV, MI
- Testing of RCCBs which are suitable for pulsating residual direct and alternating current; testing is conducted with positive or negative half-waves
