Control Cabinets

How Does Dynamic Ratings Support OEMs During Factory Testing?

Dynamic Ratings manufactures control cabinets with all instruments needed for factory testing, fully configured for the specific transformer prior to shipment, and provides direct support to the OEM throughout that process. If you consider the volume of cabinets placed across all transformer OEMs, it is cost justifiable to fully integrate the products, eliminate redundant components and make the system more cost efficient and reliable.

Transformer OEMs have their own standardized components and designs. It is often easier for them to utilize their own standards and add in additional customer specific components over the top of their standard design without truly integrating the equipment. If they are only building one transformer, this makes sense as the engineering cost outweighs the benefit of simplifying the design. But if you need more than one transformer, it is justifiable to standardize the system.

How Do Custom Control Cabinets Simplify Future Support?

Control cabinet instruments and sensors designs are tracked by Dynamic Ratings with reference to the serial number of the transformer. Once commissioned, the substation name is added to the records. If there is ever a need to locate “all control cabinets that have the following component or setting or logic or …” this detail can be easily retrieved.

Can Custom Control Cabinets Make Retrofits Easier?

Old transformers that are being updated to add monitoring or need new control cabinets installed due to aging wiring can utilize the same common control cabinet. Often it will be cheaper and easier to replace the complete control cabinet instead of adding new cabinets and interconnecting the new monitoring equipment. In place of complicated wiring diagrams that are redlined with all the changes, new drawings would provide better accuracy, while avoiding much of the consulting engineer cost.

Security

Help Control Your Supply Chain with Custom Transformer Control Cabinets

Managing the supply chain for digital equipment is a concern for a growing number of utilities. NERC CIP-013 addresses many aspects of supply chain risk management. However, digital equipment can be often overlooked when assessing supply chain management.

We will:

Support the OEM: Dynamic Ratings manufactures the control cabinets with all of the instruments needed for factory testing. All of the instruments are configured as needed for that transformer prior to shipment and Dynamic Ratings provides any support for the OEM.

Secure the Device: Dynamic Ratings will provide a second set of pre-configured instruments to the end utility for their security testing. Once the security testing is completed, these instruments will be brought to the job site by the utility.

Reclaim and Prepare for the next: Dynamic Ratings will reclaim the transformer factory test controls (bringing them back for use with the next transformer order) and will install the security verified instruments.
