Embodiments provided herein are directed to an improved way to access and increase the area of an electrical distribution device provided for cable pulling and cabling. A rotatable section, on which several electrical components of the electrical distribution device are attached, can be rotated away from the cabling area as a single unit. This permits easier access to the cabling area and increases the size of the cabling area, which results in less time required to pull cables and wire the electrical components of the electrical distribution device.

A method for installing a heavy and bulky switching module, in particular a static transfer switch, in an electrical cabinet, by way of an installation kit to make the switching module easily removable and interchangeable, regardless of its size and weight. The electrical cabinet is equipped with the installation kit including at least two support rails, extendable between an extended position outside, and a retracted position inside, the electrical cabinet, and forming two parallel rolling paths. The switching module is equipped with rollers in two parallel rows, arranged to circulate on the rolling paths to enable movement of the switching module relative to the electrical cabinet by pushing and pulling with minimal effort. A raised transport pallet is also used to facilitate handling of the switching module outside of the electrical cabinet by a simple industrial truck, without resorting to a lifting device.

Systems, apparatus, methods, and techniques of assembly of discrete modules of a control panel are disclosed. The modules can be independently wired, tested, and installed into a control panel. Module definitions are defined specifying components to perform the electrical function, a mechanical arrangement of the components, electrical connections, and logical interactions of the module. A bill of materials can be generated based on a designation of a set of modules for a control panel and the module definitions. Modularly assembled control panels are disclosed. An assembly frame is described herein for temporarily mounting components of a module for independent assembly of a control module and for eventual removal and installation into a control panel frame. The assembly frame may include a faceplate frame and side frames and temporary mounting features.

A modular HVDC platform and a method for constructing the same are disclosed herein. The modular HVDC platform has a topside disposed on a structural jacket. The topside includes a first rectifier module, a second rectifier module, and a utility module. The first and second rectifier modules have equipment for converting AC power to DC power disposed therein. The utility module contains equipment for supporting the operations of the rectifier modules. Each of the rectifier modules and the utility modules can be fabricated and commissioned onshore prior to installation on the structural jacket at an offshore location.

A switchgear system includes a switchgear frame and a truck carrying a circuit breaker, which includes a breaker housing, a fixed electrical contact and a movable electrical contact mounted within the breaker housing, an actuator piston connected to the movable electrical contact, and a drive assembly coupled to the actuator piston. A sensor circuit is mounted on the switchgear frame under the truck and aligned with the circuit breaker and configured to acquire displacement data of the actuator piston when in a contact testing position. A controller is coupled to the sensor circuit and configured to receive the displacement data and determine electrical contact erosion within the circuit breaker.

A distribution board shield. The distribution board shield includes a drape formed of an elongated non-conductive material having a top end, a bottom end, a rear surface and a front surface. A connector is used to attach the drape within a distribution panel box so that the drape covers exposed bar buses, breaker busses and wires within the working area.

A switchgear or control gear includes: a first compartment; at least one removable module; a plurality of main switchgear or control gear components; and a plurality of auxiliary switchgear or control gear components. The plurality of main switchgear or control gear components are sub-divided into a first group of components that have a lifetime greater than a threshold level and a second group of components that have a lifetime less than or equal to the threshold level. The plurality of auxiliary switchgear or control gear components are sub-divided into a first group of components that have a lifetime greater than the threshold level and a second group of components that have a lifetime less than or equal to the threshold level.
