Urban Mining in San Marcos, TX is a fully integrated facility producing and manufacturing magnets. The plant consists of four 2000kVA Utility Transformers powering 4 independent switchboards via Transfer Switches. The emergency side of the Transfer Switches are connected to a Standby Generator Switchboard capable of powering the plant via the standby generator switchboard. MTX working in conjunction with Hill Country Electric in San Antonio was able to supply the following to MEG of the Austin Office which is the main GC for the plant.Click to expand for details
An initial Short Circuit Evaluation for the entire plant with a maximum short circuit estimated from the full load amps of the system for each Switchboard.
Based on the selected protection equipment selected in the switchboards a full protective device coordination was provided, coordinating with Standby Generator Switchboard as well.
A power factor study was completed for each switchboard with the given 2000 kVA Transformer and the appropriate capacitor banks were calculated in order to achieve a 0.98 Power Factor for all operations, meeting the Utility Power Company Power Factor Requirements.
