Trace can provide a wide range of commissioning solutions for your next start-up. Factors such as power equipment mishandling during transit, poor installation, or manufacturer defects could cause the equipment to fail. Acceptance testing prevents failure events from occurring, and is a crucial step prior to energizing while serving as a benchmark for future equipment evaluation and testing. Proper acceptance testing provides assurance that your systems will perform satisfactorily while minimizing downtime and maximizing life expectancy.
Acceptance testing provides:
- Baseline data for future testing and maintenance needs
- Equipment installation damage assessment
- Equipment compliance verification
- Manufacturer design verification
Non-contact infrared scanning is the most applicable method for non-destructive, preventative, and predictive maintenance of switchgear. The scanning of the systems fuses, bolted connections, breaker panels, and electrical cabinets can determine if these components require further investigation before impending issues from overloading occur. Here at Trace, our thermography certified technicians use the latest in infrared technology to quickly determine if there are any problems as well as the cause.
Benefits if IR Scanning:
- Analyze load conditions of switchgear quickly
- Determine loose connections without torqueing
- Non-destructive method for testing cable terminations
Protective relays have evolved from their mechanical beginnings to the multifunctional microprocessor based machines being used in service today. With the growing multitude of manufacturers and relay variations, it is imperative that the testing scope be carried out by relay technicians with a strong familiarity of these devices which Trace employs in the field. Functional checks, acceptance testing, in-service testing, and tripping scheme verification (Line to Line) tests ensure the relays correct operation from initial delivery to installation and periodic functionality. Our test procedures abide by NETA and manufacturer specifications to accurately prove each function and prevent unintended trips or alarms.
The periodic testing of your systems circuit breakers is essential to not only the efficient protection of downstream equipment, but the safety of personnel as well. Regularly including this type of testing in a maintenance program ensures the proper mechanical and electrical operation of low, medium, and high voltage circuit breakers. Using the latest in testing equipment where primary injection testing is not necessary, we carry all circuit breaker manufactures secondary test sets as well. All tested breakers are checked for contact resistance, insulation resistance, and are thoroughly cleaned, lubricated, and mechanically operated.
Testing of Circuit Breakers:
- Tests can be performed on-site or in-shop
- Encompass’s entire trip unit operation
- Verifies correct timing with coordination study
The tripping technology of circuit breakers is progressively becoming micro-processor based, and any protective device not updated with this technology is at risk of causing damage to the equipment its protecting. In addition to repairing and updating circuit breakers, Trace can extend the useable life and increase the reliability of obsolete circuit breakers. We have experience in PT/CT sensor replacement, wiring catalogue changes, trip unit upgrade installations, insulative barrier replacement, and mechanical repairs. The remanufacturing of circuit breakers is ideal when considering the costs involved with purchasing newer models.
One of the highest priorities of a facilities manager is the diligent maintenance of the systems transformers. Annual testing can prevent short circuit faults, liquid contamination, flashover, internal arcing, core failure, and other major transformer failures. Even in ideal environmental conditions the transformers insulative system should be monitored annually. The trouble free service of your power transformer is dependent on proper maintenance, and Trace provides all of the services required to maintain the life of your transformer.
Types of XFMR Tests:
- Insulation Resistance
- AC/DC hi-pot
- Transformer turns ratio (TTR)
- Insulation power factor
- Sweep frequency response analysis
- Leakage reactance
- Insulating liquid analysis
- Dissolved gas analysis
- Winding resistance
- Tap changer
Trace provides an array of testing on all types of medium/high voltage cables. Diligent testing of cable installations is critical to prevent a foreseeable disaster from occurring. Several factors could attribute to cable failure including the presence of inclusions or cavities in the insulation due to manufacturer error, improper installation, overloading, tracking, or extreme temperature fluctuations. The integration of a cable testing program in your facility maintenance plan is crucial for fault prevention.
Trace offers include:
- Commissioning of new cables
- Re-Commissioning of repaired cables
- Insulation integrity tests
- Assessment of aging condition
- Dielectric breakdown
- Dielectric withstanding voltage (AC/DC Hi-Pot)
- Very low frequency (VLF)
- Partial Discharge
