HV SAFETY AND QUALITY IN INDUSTRIAL SYSTEMS & POWER GENERATION & DISTRIBUTION SYSTEMS & CONSTRUCTION SITES
High conductivity of the energy supply lines ensures their low energy loss while on opposite, the points with higher resistivity results in increased energy losses and, due to possible overheating, can cause a fire. Therefore all such points, like circuit breakers, switches, fixed joints and similar have to be regularly checked on their low resistivity.
ADVANTAGES
- Wide measurement range starting at 1 nΩ;
- 4-lead Kelvin testing method together with automatic bidirectional procedure ensure very high accuracy of test results (0.25 %);
- Battery powered but still lightweight and portable.
GENERAL FEATURES
- Four measuring modes: Automatic, single, continuous and inductive;
- Automatic thermal EMF elimination: with automatic bidirectional measurement;
- Temperature compensation: measured resistance can be adjusted according to ambient temperature, which can be entered manually or measured by external probe;
- Custom limits: limits can be set for PASS/FAIL evaluation of test results;
- Built-in memory enables storage of large amount of test results;
- Stored test results can be via RS232 or USB interface transferred to the PC with software, which enables downloading, review, analyses and printing of the test results.
APPLICATIONS
- High, middle and low voltage circuit breakers;
- High, middle and low voltage disconnecting switches;
- High current bus bar joints;
- Wire & cable resistance;
- Welding joints;
- Motor and generator windings;
- Transformer windings;
- Aircraft frame bonds;
- Rail and pipe bonds;
- Lightning conductor bonding.
