Medium Voltage Transformers External Visible Loadbreak Option External visible loadbreak option Reduce maintenance and operating costs with the external visible loadbreak option. This new option offers easy access to verify isolation of internal transformer circuitry without exposure to the risk of dangerous arc flash in the low voltage transformer compartment. Order your next transformer with the external visible loadbreak option for easier and safer transformer operation. System challenge Nearly every maintenance procedure requires verification of visible disconnect and grounding in the electrical circuit before working on a piece of medium voltage equipment. Every day operators are exposed to the risk of dangerous arc flash when breaking load inside the transformer compartment. In addition, maintenance on traditional three-phase pad-mounted transformers can be a time consuming and costly process. The Eaton’s Cooper Power Systems Solution With the external visible loadbreak option from Eaton’s Cooper Power Systems, operators can easily and safely verify an electrical disconnection through an external viewing window. The external visible loadbreak switch box mounts on the side of the transformer, away from live circuits. The viewing window allows for a clear view *The transformer tank must be externally grounded of the disconnected switch without having to go into the live cabinet. Staying out of the transformer cabinet reduces the need for wearing additional protective equipment. An authorized individual can simply open the the externally operable loadbreak switch to easily verify, through the external viewing window, that the low voltage bushings have been de-energized. The on/off/ground feature also allows the end user to internally ground the transformer windings to the tank, using the loadbreak switch.* Reduce time in the field • Simplified workplace safety and operating procedures • Reduced periodic maintenance expense Increased safety • Disconnect status verification • Safer loadbreak operation • Convenient tool that simplifies operating procedures • Eliminates need to break cable terminations • Creates a safer work environment The visible loadbreak assembly includes: Typical applications: Large viewing window for quick verification of circuit isolation • Data centers • Rotary handle for operating the isolating contacts • Mining, oil and gas • Manufacturing and industrial • Gauges mounted on box, shielded with optional padlockable cover, for easy access • Wind and solar • Military and educational campuses • Covers for switch, viewing window, and gauges not shown Product Scope • Three-phase pad-mounted transformers • Applications up to 3 MVA • Voltage class: 15 through 35 kV (150 kV BIL) • Envirotemp™ FR3™ fluid (Indoor/ Outdoor*) or mineral oil filled • Continuous current: 600 A maximum • Option available with external gauges (shown below) 4 3 5 2 6 1 1. 2. 3. 4.
