Megger NIM 1000-SET Network Impedance Tester
Megger's NIM 1000 is a self-contained, portable test system designed for measuring the loop impedance in an LV grid, allowing technicians to pinpoint malfunctions before they become a serious issue.
Megger NIM1000 - Impedance meter
With the Megger NIM 1000, you'll be able to find weak contacts, expose hidden flaws and trigger load-sensitive and neutral faults. Multi-phase measurements are possible, calculating the impedance of the neutral conductor to detect defects which may cause severe safety issues (depending on the grounding conditions of the grid under test). In multi-phase mode, the NIM 1000 will also automatically switch between test points for ease of use.
When testing, the NIM1000 performs many different tasks. It can measure current capacity under real-life conditions, determine voltage dip resulting from given loads and is suitable for testing power supply lines, cables and busbars. All of these parameters combine together to give you a comprehensive snapshot into the operation of the grid and help you to determine areas where power quality and potential issues can be improved upon. It also gives you comprehensive and reliable evaluation of the power grid in terms of current load capacity and voltage fluctuations when under load.
Megger's NIM 1000 measures grid impedance of phase and the neutral conductor up to the 10th harmonic. This ensures that you can determine complex impedance even in situtations where electronic loads and converters are generating strong harmonic currents.
Wherever you're working, the Megger NIM 1000 is ready for the job thanks to compact design, built inside its own hard carrying case. The interface is developed entirely for the needs of LV utilities and for technicians working on complex tasks on LV grids.
