SEW 1805ER Analog Earth Tester
Perhatian!
Spesifikasi SEW 1805ER Analog Earth Tester
High quality Tau Band movement.
Capable of measuring earth voltage ( Vac) . 2mA measuring current permits earth resistance tests with tripping earth leakage current breakers in the circuit under test. Test leads are supplied as standard accessories for simplified two-wire measuring system. Battery operated. Battery life indication EN/ IEC 61010-1 CAT III 150V.
Calibration performed with supplied test leads. WHY " GROUNDING TEST " IS NECESSARY ? " Grounding " has a few different purposes, such as for safety and for the stability of the electrical circuits. Listed below is more info about it.
1. Power system to the ground: As shown in figure, the purpose is preventing the secondary side from the damage of the primary side. It' s necessary for user' s safety.
2. Equipment to the ground: Connect equipments or shells to the ground. The purpose is protecting the user from the leakage of the equipments.
3. Electrical signal to the ground: Set up a " Zero volt " reference point or a loop path for all different signals. The purpose is for correct action or measuring.
4. Grounding for shielding: Top prevent static electricity. To prevent noise, electromagnetic interference ( put shielding) . Shielding room, cable and communication wires to the ground, equipment' s guard terminals to the ground, power transformers and filters to the ground.
