Abstract
A power cable measurement system for facilitating measurements of a power cable terminated at an electrical substation and connected to an overhead busbar, including: a first movable structure provided with a first busbar connector, and a measurement equipment connector device configured to be electrically connected to the first busbar connector and to measurement equipment, wherein the first movable structure is configured to be maneuvered between a default lowered position in which the first busbar connector is disconnected from the overhead busbar, and a temporary elevated position in which the first busbar connector is set in electrical connection with the overhead busbar to provide an electrical connection between the overhead busbar and the measurement equipment connector device.

A power cable measurement system for facilitating measurements of a power cable terminated at an electrical substation and connected to an overhead busbar, comprising:
- a first movable structure provided with a first busbar connector, and
- a measurement equipment connector device configured to be electrically connected to the first busbar connector and to measurement equipment,
- wherein the first movable structure is configured to be maneuvered between a default lowered position in which the first busbar connector is disconnected from the overhead busbar, and a temporary elevated position in which the first busbar connector is set in electrical connection with the overhead busbar to provide an electrical connection between the overhead busbar and the measurement equipment connector device.
A cable termination system for an electrical substation, comprising:
- a power cable,
- a cable termination device connected to the power cable, wherein the cable termination device is configured to be connected to an overhead busbar of the electrical substation, and
- a power cable measurement system having:
- a first movable structure provided with a first busbar connector, and
- a measurement equipment connector device configured to be electrically connected to the first busbar connector and to measurement equipment,
- wherein the first movable structure is configured to be maneuvered between a default lowered position in which the first busbar connector is disconnected from the overhead busbar, and a temporary elevated position in which the first busbar connector is set in electrical connection with the overhead busbar to provide an electrical connection between the overhead busbar and the measurement equipment connector device.
A method of performing a measurement of a power cable terminated at an electrical substation and connected to an overhead busbar, by means of a permanently installed power cable measurement system comprising:
- a first movable structure provided with a first busbar connector, and
- a measurement equipment connector device configured to be electrically connected to the first busbar connector and to measurement equipment,
- wherein the first movable structure is configured to be maneuvered between a default lowered position in which the first busbar connector is disconnected from the overhead busbar, and a temporary elevated position in which the first busbar connector is set in electrical connection with the overhead busbar to provide an electrical connection between the overhead busbar and the measurement equipment connector device;
- and
- wherein the method comprises:
- a) disconnecting the power cable from the substation,
- b) connecting the power cable to ground,
- c) maneuvering a first movable structure provided with a first busbar connector electrically connected to a measurement equipment connector device from a default lowered position in which the first busbar connector is disconnected from the overhead busbar to an elevated position in which the first busbar connector is set in electrical contact with the overhead busbar to provide an electrical connection between the overhead busbar and the measurement equipment connector device.
