A system for distribution transformer monitoring may comprise a distribution transformer that includes a transformer fluid tank, a monitoring unit that includes a plurality of sensors, wherein the monitoring unit is coupled to the distribution transformer, and wherein the plurality of sensors comprises a fluid sensor that includes a sensor probe that extends out of the monitoring unit into the transformer fluid tank of the distribution transformer, and a communication unit coupled to the distribution transformer and communicatively coupled to the monitoring unit. The monitoring unit may further comprises a sensor module to receive sensor data from the plurality of sensors, a storage module to store the sensor data in an internal data storage device of the monitoring unit, an analysis module to analyze the sensor data to determine generated data, and a communication module to communicate the sensor data or the generated data to a remote computing device.

A hardened inductive device and systems and methods for protecting the inductive device from impact is provided. The inductive device is hardened with protective coating and/or an armor steel housing. The hardened inductive device is protected from impact by an object such as a bullet and leakage of dielectric fluid is prevented. Acoustic and vibration sensors are provided to detect the presence and impact, respectively, of an object in relation to the inductive device housing. The measurements of the acoustic and vibration sensors are compared to thresholds for sending alarms to the network control center and initiating shut-down and other sequences to protect the active part. The acoustic sensor results are utilized to determine the location of origin of the projectile.

Unique systems, methods, techniques and apparatuses of a modular power transformer are disclosed. One exemplary embodiment is a matrix power transformer including a plurality of block assemblies each including a plurality of transformer modules, each transformer module including a primary winding coupled to an input and a secondary winding coupled to an output, the inputs of each transformer module in one block assembly being coupled together and the outputs of each transformer block being coupled together. One of the secondary windings includes a plurality of taps structured to be selectively coupled to the output of the associated transformer module assembly or another secondary winding of the associated module assembly.
