Medium-voltage switchgear control, online contact temperature monitoring and overvoltage protection.
Motor protection, power metering and cabinet environment control for factories and mining sites.
Reliable distribution monitoring and dry-type transformer temperature control for large facilities.
Inverters, PV combiner and storage cabinets need overvoltage protection and environmental control.
Pumping stations and hydro plants rely on motor protection and switchgear monitoring.
