SEW 1824 LP LOOP / PSC / EARTH Tester
The 1824 LP is a new generation of instruments for the testing of electrical installations. It has a built-in Earth tester which does not requires the use of poles or long wires. This instrument is useful for fault-finding or commissioning of electrical installations. This new instrument uses a three wires unique principle of operation.
Features
- Microprocessor-controlled.
- Measures Earth Resistance without the need for poles in the ground or external measuring wires.
- Earth measurement uses the real earth current path and the current generated by the electric network, without the need for any disconnection.
- The Earth Resistance displayed is exactly the earth resistance that the earth current will need to go through if an earth fault occurs. (you do not need to add all the bonding points and connection paths)
- Single one smart push button operation; ON, Scroll through results and menus.
- Checks wiring integrity (LEDs).
- Auto-off / Auto-ranging (software range).
- Color-coded test leads.
- Combined prospective short circuit current, loop, and earth tester.
- Loop test for L-E and PSC between L-N.
- Voltage test L-N.
