Dissolved gas analysis (DGA) is widely used to monitor the condition of transformers and other pieces of oil-filled equipment in service. Wrong diagnoses may be drawn, however, if the DGA results coming from the lab are not accurate. For instance, an electrical fault may be mistaken as a thermal fault, which may have serious consequences for the equipment. Several CIGRE and IEC round robin tests (RRTs) have shown that the repeatability (precision) of DGA labs is generally good, but that their accuracy (deviation from true value) is often poor.

LTC position monitors are IEDs that are used for monitoring a transformer’s tap position and changing it remotely based on fluctuations in the power load. The device converts the output of an electromagnetic position or displacement sensor (synchro transmitter) to a user-definable panel display and electrical output. The INCON Model 1250 for example employs a proprietary synchro conversion technique that is performed entirely in preprogrammed software. This approach uses few electrical components, thus ensuring a more stable and reliable output at a very reasonable cost.

From a number of perspectives the active devices in an electric power delivery system, the circuit breakers, can be characterized as the weakest links in the network, as opposed to the passive components such as lines and transformers. That said, the unerring action of switching devices is critical to power delivery quality and reliability.
