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.…
A transformer at an unattended site can be difficult to protect simply because there may be nobody there when something happens. This is a common situation in rural distribution networks, irrigation systems, mining areas, construction sites, and remote substations. A…
Transformer theft monitoring for remote substations is the practice of instrumenting an unmanned site so that an intrusion becomes a dated event at a control room rather than a discovery made weeks later by a patrol, and it is designed…
