How to Address Renewable Energy Connection with Integrated Switchgear

NOJA Power OSM Recloser

Grid scale solar power plants are good for the environment, and good for business. Not only do they displace the generation demand for fossil fuels, but once they’re built, it costs virtually nothing to generate revenue. As the cost of installations come down, so too do the payback periods, and so globally we see a proliferation of these installations.

Detecting Earth Faults on Isolated and Resonant Earthed Networks

NOJA Power OSM Recloser

Isolated and resonant earthed electricity distribution networks present a challenge for detecting single line to ground faults. Despite this fault classification being the most common on overhead networks, it is also the most difficult to detect in these network topologies.

However, this is a solved problem.
