The State of Mexico, the state that wraps around Mexico City, has one of the most diverse manufacturing bases in the country. The industrial belt north of the capital, in municipalities such as Tlalnepantla, Naucalpan, Cuautitlán Izcalli and Tultitlán, mixes pharmaceutical, chemical, plastics and food plants. To the west, the Toluca–Lerma corridor adds vehicle assembly, auto parts and beverages, and large distribution centers line the highways leaving the capital.
Many of these plants have been running for decades. Their substations, transformers and medium-voltage cables age while demand keeps growing, which is exactly where preventive electrical testing pays off. A transformer failure in a plant fed at medium voltage can mean days without production while a replacement is sourced, and older cable runs often have splices that nobody has inspected since they were installed.
Industries and their typical tests
- Pharmaceuticals: calibration of pressure and temperature transmitters in validated processes, and reliable power for cleanrooms.
- Food and beverage: transformers and motors on bottling and packaging lines, refrigeration and boilers.
- Chemicals and plastics: extruders and molding machines on variable frequency drives, plus areas that require extra care during maintenance.
- Plants with their own substation: testing of transformers, breakers, protection relays and underground cables.
- Logistics centers: forklift chargers, high-bay lighting and backup systems.
Key services for the State of Mexico
In industrial substations with years of service, transformer and current transformer testing (turns ratio, winding resistance, insulation) reveals the true condition of the equipment. It pairs well with transformer oil testing witnessed by the client, which is helpful when results must hold up before an insurer or an audit.
Underground medium-voltage feeders are assessed with VLF testing of medium-voltage cables, and protection schemes with substation relay testing. For pharmaceutical and chemical clients we offer laboratory calibration of pressure, temperature, flow and HART signals.
When a capacitor bank or harmonic filter needs to be justified, three-phase power quality analysis provides the data. If your plant is in the Toluca valley, see our page on electrical testing in Toluca.
How we serve the State of Mexico from Monterrey
CreativeIT works out of its Monterrey laboratory and has no facilities in the State of Mexico. For substation work, our engineers travel to your plant and operate within the lockout or planned shutdown set by your maintenance team, following the safety practices of NOM-029-STPS, Mexico’s standard for electrical maintenance safety.
Process instruments can be shipped to the lab for calibration and returned with their report, which avoids taking several devices offline at once in regulated processes. Rental test equipment such as power analyzers or turns ratio testers ships by courier to your site.
All results are delivered with a work plan, protocol, photos and video, and with traceability to NIST, so the file is complete for your ISO 9001 quality system or your customer’s review.
