Abstract: Methods and systems for creation of reviews are described. In some examples, an affinity between a reviewer and a customer is determined. A question is received from the customer, related to a merchant offering. The reviewer is provided with an option to create a new review based on the question, the option being provided to the reviewer based on the determined affinity.

Abstract: Methods and systems for presenting a review are described. A set of reviews is presented in response to a first event associated with a first merchant offering. The set of reviews include a plurality of selected reviews associated with the first merchant offering. At least a first review in the plurality of selected reviews is selected, from a plurality of stored reviews, based on a match of one or more attributes between a profile of the first customer and a profile of a first reviewer associated with the first review.

Abstract: A retrofit diverter switch which has a mechanical and electrical interface that is compatible with the existing designs is provided. The diverter switch may include a vacuum switch. The feature where the mechanical and electrical interface is compatible enables a retrofit from traditional On Load Tap Changers to a vacuum based on Load Tap Changers. The diverter switch may be retrofitted into existing tap changer housings. Retrofitting from traditional to vacuum based, traditional to vacuum based and up rating, and vacuum up rating may be possible. Also, the diverter switch may include modular components that allow for easy customization of the diverter switch for different applications.

Abstract: A diverter switch with an operating member and an electric circuit. The electric circuit has a main branch and a resistance branch connected in parallel with the main branch. Each branch includes a contact and a vacuum switch. The resistance branch also includes a resistance. The main rotary selector contact is always operated before the resistance contact. The operating member is arranged, during operation, always to rotate the main contact in one and the same direction of rotation. Also a corresponding method for operating a diverter switch and use of such a switch.

Abstract: A resistor for electric high-voltage apparatus, especially for connection to a diverter switch in an on-load tap changer for a high-voltage transformer. The diverter switch and the resistor are arranged in a housing with transformer oil. The resistor includes a number of resistor elements, wherein each resistor element includes a resistive element, arranged in a frame, which are electrically interconnected by a connection member. The frames are designed to enclose resistive elements that include spring elements formed from spirally wound resistance wire. Connection members include a connection plug. A method of mounting a resistor for electric high-voltage apparatus.

Abstract: The invention relates to a diverter switch with an operating member and an electric circuit. The electric circuit has a main branch (1) and a resistance branch (2) connected in parallel with the main branch (1). Each branch comprises a contact (11, 21) and a vacuum switch (12, 22). The resistance branch (2) comprises, in addition, a resistance (30). The main rotary selector contact is always operated before the resistance contact (21). According to the invention, the operating member is arranged, during operation, always to rotate the main contact (11) in one and the same direction of rotation. The invention also relates to a corresponding method for operating a diverter switch and use of such a switch.
