Find Insulation Monitoring for Different Industries
Critical life safety & public service systems
Insulation monitoring device is used in critical life safety and public service systems to ensure that the system operates without interruption (zero interruption) in the event of a first insulation failure, thus protecting the lives of passengers, patients, or the public and ensuring the continuity of critical services. Common applications include: medical (such as operating rooms and ICUs), elevators, rail vehicles, airports, and traffic lighting.
New Energy & Complex DC Networks
In new energy and complex DC networks, insulation monitoring relays are primarily used to address large leakage capacitances and complex current waveforms in the system, ensuring accurate and reliable insulation monitoring in DC links with high fire risk. Common applications include charging piles, automotive, marine, photovoltaic systems (solar energy storage), renewable energy (solar panels and wind turbines), DC circuits, and industrial-grade DC/DC systems (DC power supply systems/DC charging systems in power plants, substations, and other power engineering projects).
Harsh Environments and Mobile/Auxiliary Power Supplies
In harsh environments and with mobile/auxiliary power supplies, IMDs need to possess high robustness and interference immunity to ensure continuous early warning and safety protection even when field insulation is highly susceptible to damage. Common scenarios include mobile power generation and industrial systems (including general industrial auxiliary power supplies), and the mining industry.
