Deskripsi
Jual SEW 1824 LP Digital LOOP/PSC/EARTH Tester
Deskripsi SEW 1824 LP
| 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)
● 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.
