Projects
Damatt Engineering, Inc. provides high-quality electrical and control systems engineering, programming, and design services for a wide variety of industrial clients. Our projects have included the design of new high-voltage substations, electrical distribution systems, medium-voltage motor and equipment protective relaying, and state–of-the-art process control systems.
Here is a sampling of our completed engineering, integration, and specialized projects:
Specialized
Premium Sand Plant
Graniterock – Aromas, CA
Damatt provided complete electrical engineering, PLC and HMI programming, and commissioning services for a new sand processing plant. A new switchboard with modern electric trip units along with a 3000KVA transformer was installed. The existing electrical room was modernized to provide for the required power needs of the six-floor processing plant. Horizontal and vertical raceways were engineered to distribute power and control system cabling from the electrical room and throughout the plant superstructure. Detailed P&ID’s were developed and sensors were specified for the complex process requiring twenty fluid control loops. A custom recipe system was developed and deployed between the HMI and PLC.
Hydro Powerhouse No. 3 – New Generator Excitation System, Controls, and Protective Relaying, Generation Plant No. 3
Southern California Edison – Kaweah, CA
Damatt provided electrical design to Southern California Edison design standards for a hydro-electric generating station which was originally built in the early 1900’s. Due to the absence of electrical drawings, extensive field investigation was required to document existing wiring and control systems before detailed design could begin. Damatt provided complete AC and DC elementary drawings for the generator protection, control and excitation schemes, the step-up transformer bank protection, and the transmission system intertie circuit breaker. Damatt provided complete point-to-point wiring diagrams for all new relaying and control panels which allowed the panels to shop fabricated. The scope included field construction support, and start-up and commissioning engineering
New 2,500 HP, 4kV VFD Induced-Draft Fan Drives
Lehigh Permanente Cement – Cupertino, CA
Damatt provided complete electrical design for two new 2,500 HP, 4.16 kV induced-draft fan drives. The scope included development of procurement specifications for the drives, bid analysis, and purchase recommendation. Damatt provided electrical, control system, and instrumentation design to interface the new drives into the existing cement plant Honeywell DCS and Allen-Bradley PLC based control systems. Construction management, PLC and DCS programming, drive interface configuration, and start-up and commissioning services were included in the Damatt scope.
