The Earth Loop Impedance Tester ELT-S has been engineered especially for measuring the phase rotation, earth loop resistance via neutral (N), earth loop impedance via phase (L) and net impedance of LV-installations, all according to the EN 61557 regulation. The instrument is fully electronic and can perform line and loop impedance on single- or three phase systems. It is also possible to measure the loop resistance between neutral and earth without tripping the RCD's.
Following tests
Earth loop impedance
Earth loop resistance between neutral and earth
Prospective short circuit current (Ipsc)
Net impedance between phase and neutral lines and between two phase lines on a three phase system
The condition of the protective earth potential (safe or dangerous)
Voltage
Frequency three phase rotation field
The ELT-S has an internal memory with 500‑locations for storing the measured values. These stored values can easily be transferred to a PC via the RS232 port.
