Since 2012, 1st Electrical Measurement Laboratory LLC (1EL) has been a mobile electrical laboratory in Moscow and the Moscow region.

We perform:
- circuit breaker loading;
- insulation resistance measurement;
- ground resistance measurement;
- transition resistance measurement;
- soil resistivity measurement;
- short-circuit loop parameter measurement;
- residual current device parameter measurement, etc.
- lightning protection resistance determination (soil resistivity, grounding, ground resistance measurement).
- and after taking measurements, we provide protocols (Technical report).

We also perform: energy audit, high-voltage testing, design and installation work.
Free visit for preliminary assessment and estimate preparation (Moscow and Moscow region).
