The present disclosure is directed to a padmount transformer. The padmount transformer includes an electrical distribution transformer housed in a cabinet that can be mounted on a ground level platform or pad. High/medium voltage connectors of the electrical distribution transformer can connect to high/medium voltage terminals of a power supply network. Low voltage connectors of the electrical distribution transformer are configured to connect to low voltage terminals of one or more loads coupled to respective renewable energy sources. The high/medium voltage connectors and the low voltage connectors are housed in the cabinet. An energy storage apparatus is housed in the cabinet and is connected with the low voltage connectors for supplying power to the loads. Power can be supplied to the energy storage apparatus by the renewable energy sources. An inverter is operable for commanding the power supply direction at the energy storage apparatus and a control unit is configured to control the inverter.

A method for calibrating voltage sensors in a switchboard, using a communication bus which comprises the following steps: i. performing a measurement using a first voltage sensor; ii. transmitting an information derived from said measurement to an electronic device, through the communication bus; iii. using said information to calibrate a second voltage sensor.

Method for on-line calibration of low accuracy voltage sensor through communication bus

A method for controlling the closing operation of a switching device, which is disposed on an electrical network connected to an inductive component. The method requires first data related to the electrical characteristics of the inductive component and the electrical network. Based on the first data, on a predefined first storage device containing opening and closing operation sequences, a first predefined opening operation sequence is selected. Then, based on the first predefined opening operation sequence, on the first storage device, a first predefined closing operation sequence is selected.

A bistable permanent-magnet actuator is disclosed having a tailored switching/position force characteristic, with an adequate, modifiable holding force in the end positions. The actuator is characterized in that the yoke is formed by two parts that are mounted so as to face each other and are separated by two gaps. The dimensions of the air gaps may be tailored to obtain intended characteristics.
