Deterministic sensing architectures engineered for high-voltage substations, generation turbines, and power distribution grids. Combines wideband acoustic corona and arcing indicators, synchronous tri-axial vibration, and thermal telemetry designed for IEC 61850 and IEEE standards compliance.
Electrodynamic forces from repetitive fault currents degrade transformer clamping structures, causing core laminate loosening and winding displacement. Our wideband vibration sensors track 100 Hz / 120 Hz fundamental harmonics and high-order magnetostrictive spectral signatures to detect structural mechanical degradation to support early maintenance action.
Audible corona and arcing indicators on transformer tanks and switchgear. Utilizing wideband acoustic sensing (20 Hz – 10 kHz), our nodes isolate micro-arcing energy from ambient substation hum with reduced false-alarm rates. Full PD detection requires AE (20–300 kHz) or UHF sensors — available via custom ODM.
Turbine generator sets undergo severe thermal and mechanical stresses during ramp-up and peak load cycling. Continuous casing vibration trending on turbine-generator auxiliaries and gearboxes complements API 670 proximity-probe protection systems; ISO 20816-2 severity evaluation.
Mechanical linkages, springs, and hydraulic trip actuators in SF6 circuit breakers experience stiction and lubrication drying over decades. Breaker operation vibration-signature and timing analysis alerts asset managers to sluggish trip mechanisms to support preventive maintenance.
