SEW 1824 LP Digital LOOP/ PSC/ EARTH Tester

Loop Testers & Electrical Network Analyzers FEATURES Ï Microprocessor-controlled. Ï Measures Earth Resistance without the need for poles in the ground or external measuring wires. Ï Earth measurement uses the real earth current path and the current generated by the electric network, without the need for any disconnection. Ï 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) Ï Displays voltage supply at the transformer( Line to Neutral) , without loading the transformer. Ï Single one smart push button operation; ON, Scroll through results and menus. Ï Checks wiring integrity( LEDs) . Ï Auto-off / Auto-ranging ( software range) . Ï Color-coded test leads. Ï Combined prospective short circuit current, loop, and earth tester. Ï Loop test for L-E and PSC between L-N. Ï Voltage test L-N. Ï Display can be customized for large orders.
