Digital Loop Tester SEW 1824LP

Fitur Digital Loop Tester SEW 1824LP:



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)

Displays voltage supply at the transformer(Line to

Neutral), without loading the transformer.

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.

Display can be customized for large orders.
