Category Condition Monitoring
Condition monitoring measures a transformer's state while it stays in service: oil condition, winding and top-oil temperature, vibration, tilt, bushing signals, and the communication path that carries them to a control room. Each measurement proves something narrow, and the value comes from how the signals are combined and trended. This section covers what online transformer monitoring actually measures, what vibration can and cannot reveal, and how remote monitoring is specified and commissioned.
Transformer winding resistance test: A Practical Guide for Load Testing
Reading the direct resistance, no-load current and the rated value, transformer winding resistance test verifies winding and magnetic circuit.
Switchgear monitoring: A Practical Guide for Substation and Plant Engineers
Switchgear monitoring tracks temperature, partial discharge and sf6 density channels of a bay, catching a developing failure before it opens.
Transformer Monitoring: Parameters, Systems & Selection Guide
Transformer monitoring helps EPC contractors, asset owners and electrical engineers assess transformer operating conditions, identify abnormal trends and make better-informed maintenance decisions. The right installation depends on transformer type, asset criticality, fault risks and the information the maintenance team actually…
Transformer Remote Monitoring Communication: GSM, 4G or NB-IoT for Remote Sites
Transformer remote monitoring communication is the telemetry layer that carries an event from a sensor on the unit to a person who can act on it, and it consists of three separate choices that are usually confused with one another:…
Transformer Tilt Detection: How It Works
Transformer tilt detection answers one question that no other channel in an anti-theft system answers: is this unit still sitting the way it was installed? It measures the attitude of a unit against a reference position recorded while the site was undisturbed,…
Vibration Based Theft Detection: How Vibration Signals Expose Transformer Theft
Vibration based theft detection is the practice of watching the mechanical signature of a transformer for the disturbances that a person causes, rather than the disturbances the machine causes itself, and it works because almost every theft attempt makes the…
