Control Panel Technical Design Guide (Thermal Condition Analysis and Optimisation): It’s very important to know the critical temperature for each device and the critical humidity level for each device. The thermal management solution must be sized according to the critical temperature of the most delicate element of the enclosure. This temperature should never be exceeded. The mean working temperature recommended for the inside of the enclosure is 35°C. This is the reference temperature for the control equipment integrated in the thermal solution.

Designing a new IEC 61850 substation architecture and solving encountered issues: The primary role of Substation Automation System (SAS) is to provide safe, secure, and reliable local/remote control and monitoring of high-voltage AC distribution and transmission stations. Historically, the Substation Automation System (SAS) at Manitoba Hydro (MH) was implemented in the substation using RTUs and redundant PLCs, with redundant computers for the local HMI and without any hardwired control backup.

25 High Voltage Transformer Tests and Commissioning Procedures (Before Energizing): When transformers are received from the factory or reallocated from another location it is necessary to verify the following: that each transformer is dry, no damage has occurred during shipping, internal connections have not been loosened, the transformer’s ratio, polarity, and impedance agree with its nameplate, its major insulation structure is intact, wiring insulation has not been bridged, and the transformer is ready for service.
