Electrical Field Services | Equipment Repair, Machine Maintenance & More
Electrical field services from RESA Power involve a range of essential systems support, from inspections to testing, all aimed at ensuring the health and longevity of electrical systems. Inspections performed by qualified electrical field service technicians help identify potential issues before they become problems and potentially dangerous. Testing services provide accurate electrical system measurements, offering insight into its current state and identifying any weaknesses or faults.
It is essential to have regular field services performed in order to prevent malfunction or failure of electrical systems, ultimately maintaining safety and minimizing potential downtime in commercial and industrial settings. Additionally, certain industries and facilities may be required by law to adhere to specific electrical standards and regulations, making ongoing field services essential for compliance.
RESA Power offers a variety of electrical field services, from on-site testing to insulation and ground resistance testing, power quality assessment, and ARC flash assessments. Providing the testing services you need, when you need them: that’s the Power of Us.
RESA Power has more than 40+ locations, providing a network of field sales engineers and electrical field service technicians throughout the U.S and Canada. Our trained staff are industry leaders and provide high-quality maintenance and inspection of your equipment.
Field Services
Field Inspections
Our technicians will drive out to meet you in the field to perform inspections on your equipment on-site. As part of our service agreement and warranty, we aim to ensure optimum performance for the life of your transformer.
Testing and Predictive Maintenance
Because reliable performance is essential to your business, RESA will keep equipment running without interruption through our full electrical machine testing, electrical equipment repair, replacement, and maintenance services. We can help you implement scheduled preventative maintenance per our maintenance and testing guide.
Infrared Scanning Services
This noninvasive substation inspection technique uses a thermal imaging camera to detect high levels of heat — one of your transformer’s top three enemies — emitted in the form of infrared radiation. The camera can also identify cold spots that should be hot, which could indicate an early fault detection helps prevent permanent damage to your transformer, switchgear, and other substation equipment and the unplanned downtime that comes with it.
Ultrasonic Air Leak Testing
Detects leaks with a fault detector which can be indicative of larger operational issues to come, including drops in efficiency, safety issues, and whole-system shutdowns.
Ground Resistance Testing
This test will check how much the soil resists passing electrical currents. Testing like this is recommended every three years for a system in good condition with average up-time requirements by The International Electrical Testing Association.
Insulation Testing of Motors
If a motor is not put into operation immediately upon arrival, it is important to protect it against external factors like moisture, high temperature, and This will avoid damage to the insulation. Before the motor is put into operation after a long period of storage, the winding insulation resistance must be measured.
Feeder Cable Testing
The continuous rating of a fuse shall not exceed three times the ampacity of the conductors.
Power Quality Monitoring
To monitor their power, modern power plants use digital fault recorders, smart relays, voltages recorders, in-plant power monitors, and special-purpose power quality A digital fault recorder activates on fault events. Then, it records the current waveforms and voltage that caused the problem. In short, power quality monitoring monitors the quality of voltage and current produced by a power plant.
Arc Flash Assessments & Labeling
Arc flash risk assessments (and their corresponding labels) should be updated when a major modification or renovation takes It should be reviewed periodically at intervals not to exceed five years to account for changes in the electrical distribution system that could affect the results of the arc flash risk assessment.
Ground Fault Testing and Inspection
Equipment needs to be protected from ground faults — contact between an energized conductor and ground or equipment frame. RESA Power technicians conduct thorough examinations of insulation breakdowns resulting from damp, wet, or dusty environments. Grounding electrical systems provide protection against electrical faults to reduce shock hazards and lightning.
Battery Bank Testing
The main objective of battery maintenance is to ensure the battery system can meet the emergency run time requirements. Preventative maintenance must be comprehensive, consistent, and in regular intervals. RESA Power will identify any performance-related programs using any of the following: visual inspections; voltage, resistance (impedance), current and temperature measurements, and capacity testing.
SF6 Gas Testing and handling
Our gas analyzers can test the gas in your equipment for purity, moisture and by-products. RESA Power will also use our gas carts to remove SF6 from your equipment with zero emissions of the greenhouse gas, in order to replace gaskets or relocate circuit breakers. We are also here to assist with the annual reporting of SF6 gas inventories.
