Page 7: Tank Wall Kit
Tank wall kit The Tank Wall Kit consists of: Tank wall Ring Tank wall Plate J-Box – protection for tank wall Ring/Plate/connectors O-ring (comes with Ring and Plate, to be installed between Ring and Plate) Gasket (comes with J-Box, to me installed between J-Box and Plate) Bolts The components listed above are typically supplied as a kit, based on customer’s orders they can also be supplied in various combinations (only the plate, plate with J-Box, etc) -
Page 8: Tank Wall Ring
Tank wall Ring The tank wall Ring must be installed on transformer tank wall by welding process. A sealing O-ring is supplied with the Ring. The O-ring is to be installed between the Ring and the Plate, having the role of preventing the oil leaks. The Ring is supplied with threaded holes for the bolts that will be used to install the Plate on the Ring. -
Page 9: Tank Wall Plate
Tank wall Plate The Plate is designed to be mounted on DIN Ring using 8xM18 bolts that are also supplied with the Plate. The Plate comes with the optic fiber connectors already installed on it. The number of connectors supplied and mounted on the Plate is equal to number of optic fiber probes that will be installed inside the transformer. -
Page 10: Connectors
Connectors The number of Feedthroughs is at least equal to the probes that will be installed in the transformer tank. Make sure to clean up the connectors’ fiber optic ends using the cleaning tool supplied with the instrument, and make sure to keep the caps all the time on the connectors, removing them only before connecting the extensions/probes to the plate. -
Page 11: Optic Fiber Probes And Extensions
IP66 ( IEC 60529), NEMA 4, ISO 20653 Optic fiber Probes and Extensions The optic fiber cables that are delivered with the InsuLogix T system are: Optic fiber probes – consist of optic fiber with GaAs sensor and connector Optic fiber extensions – consist of optic fiber with two connectors Probes The outer jacket of the optic fiber temperature probes is made out of PTFE. -
Page 12: Extensions
Figure 10 Optic fiber in Oil Coupling (optional) with Ceramic Disk (optional) Extensions The optic fiber extensions consist of protected optic fiber cable with optic fiber connectors mounted on both ends. The extensions are used to connect the InsuLogix® T instrument to connectors that are installed on plate. -
Page 13: Installation
3. Installation There are several operations that user must follow in order to install a complete system. Some of these steps will be skipped in case of partial installation (when installing only the probes, only probes and tank wall kit, etc). The steps to be taken in order to install a complete system are: 1. - Page 14 (probe, connector on plate, the instrument’s channel or the Portable extension). If still not able to solve the problem then contact Weidmann and be prepared to inform on device the results of your troubleshooting process.

Page 17: Weidmann Smart Spacer
OEMs specific design. The probe mounting in key spacer and testing of finalized product are done at Weidmann facility, following that the OEM will receive the final product along with a Testing and Performance Certificate. This eliminates the assembly and testing processes that normally the OEM is doing before installing the optic fiber in transformer windings using key spacer solution. -

Figure 16 Examples of optic fiber probe mounting in key spacer (Smart Spacer assembly) Feedthrough connectors installation Weidmann is supplying the transformer tank wall plate with the connectors pre-installed on it. The connectors and leak-proof and is not needed to re-tighten them over transformer lifetime. -
Page 19: Verifying The Optic Fiber Continuity During Installation Process
Ideally the OEM should route the extensions through their own conduit also inside the transformer control cabinet. If this is not done then Weidmann strongly recommends that optic fiber extensions sections located inside the transformer control cabinet be clearly identified by the transformer OEM with tags as "Optic fiber - Fragile"... -
