LV electrical systems must comply with the installation rules of standard NFC 15-100.
Compliance must be guaranteed upon initial commissioning, and also after periodic inspections.
In particular, the value of the EARTH CONNECTION must be inspected.
Tohm-e can measure that value from a simple power socket.
The device can also check if the socket is wired correctly (position of phase, neutral and earth).
- Measurement using the earth loop principle
- Device designed for TT earth systems
- Earth connection measurement: 0.0 D to 2kD
- Voltage measurement: 50V to 440V (actual RMS value)
- Indication of the position of phase, neutral and earth
- Usage temperature: -20°C to +55°C
• SIMPLE : just connect Tohm-e to a power socket.
• INSTANTANEOUS : the display is immediate
No risk of failure, as Tohm-e operates without cells.
• AUTOMATIC INTERPRETATION OF RESULT :
- blue screen showing that the earth value is OK (earth <100D)
- red screen showing that the earth value is not OK (earth >100D)
• ADAPTS TO ALL REQUIREMENTS : the rotating head allows easy reading
