Online DGA monitoring vs laboratory DGA testing is not a contest between a better method and a worse one. Treating it as one is the fastest way to buy the wrong instrument. The two answer different questions, and most transformer…
By Leon Zhang, Transformer Condition Monitoring Engineer · Published September 9, 2026 · Last updated: October 5, 2026 · 9 min read DGA monitoring for power transformers is the continuous or periodic measurement of dissolved gases in transformer oil to detect developing internal…
Transformer theft prevention in Africa is a regional problem before it is a technical one, because the same controller, the same sensors and the same alarm logic produce different outcomes in Lagos, Nairobi, Johannesburg and Harare, and the variable that…
Protect pole mounted transformers from theft by matching the sensor set to the removal sequence that a pole installation actually permits, because a theft seven metres above a roadside is a different operation from one inside a pad-mounted enclosure, and…
Rural transformer theft prevention is the design of a protection scheme around the shape of a network rather than around the equipment, because on a rural feeder the patrol interval, the travel time and the load profile are all set…
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 cable cutting detection is the practice of watching the cables that serve a transformer for the moment one of them is cut, and it exists because cutting comes before lifting in almost every theft of a distribution unit on…
Transformer tilt detection is the practice of measuring the attitude of a unit against a reference position recorded while the site was undisturbed, and raising an event when that attitude changes by more than a threshold in less time than…
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…
Transformer tampering detection is the practice of catching unauthorized physical interference with a distribution transformer, such as an opened compartment, a removed cover, a forced lock or a drilled tank, before the unit is lost. It differs from condition monitoring.…
