5. Bushing Monitoring System Products
Bushing monitoring systems track the condition of these critical insulating components that extend high-voltage conductors through grounded transformer tanks. Bushing failures account for approximately 10-15% 모든 변압기 고장 중, making continuous monitoring essential for preventing catastrophic events.
Capacitance and Dissipation Factor Monitoring
Capacitance and tan delta monitoring measures the capacitance (C₁) 및 역률 (탄 δ) of bushing insulation systems. These parameters directly indicate insulation quality, with increasing capacitance suggesting moisture ingress or contamination, while rising power factor signals insulation degradation. Modern systems achieve 0.1 pF capacitance resolution and 0.001 tan delta accuracy, detecting subtle degradation trends months before failure.
Bushing Tap Current Measurement
Tap current monitoring continuously measures the current flowing through bushing capacitance tap connections. Abnormal current levels or sudden changes indicate developing insulation problems, 수분 오염, 아니면 내부 결함. Comparing tap current against voltage variations helps distinguish load-related changes from genuine insulation degradation.

Synchronous measurement enables comparative analysis between phases, identifying outliers that might indicate problems with specific bushings. Automated trending algorithms flag deviations from historical baselines or inter-phase imbalances exceeding threshold limits.
Predictive Maintenance Strategies
Bushing condition monitoring enables condition-based maintenance scheduling rather than reactive failure response. Gradual degradation patterns typically provide 6-12 months advance warning before critical failures, allowing planned bushing replacements during scheduled outages. This proactive approach prevents unplanned failures that typically cause extensive collateral damage to transformer tanks and internal components.
6. 부하시 탭 체인저 (OLTC) Monitoring Products

Deviations from normal operation patterns indicate developing mechanical problems like worn drive mechanisms, 느슨한 연결, or inadequate lubrication. Automated monitoring systems compare each operation against baseline signatures, flagging anomalies for investigation.
Operation Counter and Maintenance Scheduling
OLTC operation counters track cumulative tap changes and positions, enabling predictive maintenance scheduling based on manufacturer-specified service intervals. Modern systems record detailed operational history including date, 시간, position changes, and operating conditions for each tap change. This data supports reliability analysis and helps optimize maintenance intervals based on actual usage patterns rather than arbitrary time periods.
Contact Resistance Measurement Technology
Dynamic resistance measurement (DRM) systems inject DC current through OLTC contacts during switching operations, measuring contact resistance in real-time. Increasing resistance indicates contact erosion, 오염, or inadequate contact pressure. This technique detects contact degradation before it causes overheating or failure, enabling timely contact replacement or refurbishment.
Vibration Signal Analysis
