TRANSFORMERS - DRY & OIL FILLED TYPES
Repair Of Leaks, Bushings, Housing, Radiator Fins, Gaskets & Indicators
Our specialized transformer repair services can stop any oil or nitrogen leaks your transformers may have. We check all gaskets and seals to ensure that there are no leaks (either oil or nitrogen). We can replace damaged or corroded bushings, repair housing and fins, and repair or replace indicators or gaskets if necessary.
Installation Of Transformer Fans, Temperature Sensors, Gauges, & Nitrogen Blankets
Fans circulate air around the transformer and therefore cool the transformer oil. Temperature sensors allow a technician to monitor the temperature and perform preventative maintenance before any damages or failures can occur. In order for a transformer to properly operate for a long periods of time under heavy loads or in a heated environment, the heat must be removed from the oil and the transformer. At PowerCom we do that by cooling the environment the transformer is in and by adding the proper cooling fan kit. A nitrogen blanket over the top of the oil will displace the oxygen. This blanket forces the air out of the transformer and keeps the air from degrading the oil.
Test, Analyze, Filter, and Replace Transformer Oil
Periodically, transformers need to have their oil inspected and sent to a lab for analysis. PowerCom performs the inspections and analyzes the oil. After the samples have been taken to our laboratory, we provide accurate results that will indicate if there are any contaminants or unsafe levels within the transformer oil. If necessary, oil filtration or replacement are other services PowerCom offers.
A Transformer rewind is the complete replacement of all internal parts of the transformer. PowerCom offers a complete rewind, thus keeping the foot print of the original housing to match existing applications.
Splices and terminations are based on voltage class and cable types. There is an alternative to hand applied tape layers. Proper installation of force-fit rubber parts, cold–shrink, resins and heat shrink will duplicate your cables system’s performance electrically, thermally and mechanically.
Complete Transformer Replacement
There are times when a particular transformer has been damaged beyond repair. There are also times where a transformer has been discontinued and the parts are no longer available for purchase. If your company is finding themselves in this position, PowerCom also offers a complete transformer replacement that will fit an existing space.
CIRCUIT BREAKERS - AIR, OIL, VACUUM, & SF6
Installation & Upgrade Of Trip Units
The installation of new electronic trip units is a service we provide in order to replace old obsolete or faulty trip units. This along with a complete overhaul of the circuit breaker will increase reliability and performance of your switchgear.
Retrofit Existing Cabinets With New Breakers
As your company expands, so does your need for utilities. Old circuit breakers that have been installed may not be adequate enough to withstand the new loads. In order to save our customers money, we can retrofit your existing cabinet to accept the new circuit breaker instead of a complete overhaul of the system.
Replacement Of Circuit Breakers
If for any reason you have an old circuit breaker that needs to be replaced, we can install a duplicate breaker or install a breaker that will exceed the needs of your current system.
Supply Obsolete Parts
PowerCom has access to many discontinued or obsolete parts to all different manufacturers of circuit breakers.
Complete Overhaul Of A Circuit Breaker
Due to the combination of age and condition, circuit breakers must be taken apart and overhauled after some time to ensure that it is in proper working condition, and that the parts are not defective or broken. To take it one step further, the entire circuit breaker can be remanufactured to a like new condition.
Perform Diagnostics & Troubleshooting Of Faulty Circuit Breakers
When a circuit breaker trips it requires a trained personnel to diagnose the cause, as well as ensure that nothing within the circuit breaker is faulty. We have the diagnostic tools and experience to determine the source of the problem in a timely manner.
Troubleshoot & Test
PowerCom has trained professionals and engineers to diagnose and fix any malfunctioning switchgear as well as test the switchgear for proper operation.
Customize & Upgrade Existing Switchgear
The advancement in electrical systems in inevitable, that’s why we provide customers with the ability to tailor their system to meet the needs of the new system. Some of those services include installing controls, meters, gauges, and indicators.
Repair & Replacement Of Damaged Switchgear
Damages will occur to your switchgear over time, from normal wear and tear, accidents, or electrical faults. PowerCom has the ability to repair old or broken parts. We also have the ability to replace the entire switchgear in order to meet increasing standards.
Repair, Replace, & Add New Protective Relays
Protective relays are extremely important to protect your electrical infrastructure. They are designed to calculate operating conditions on an electrical circuit and trip circuit breakers when a fault is found. If these relays are not operating up to specifications then they need to be repaired, recalibrated or replaced. If during our troubleshooting it is found that the relay is beyond repair a replacement will be installed in its place. The addition of relays to an unprotected circuit is also a service we provide.
Test & Verify Current Transformers & Potential Transformers
There are many different components that are connected to the protective relays. In order for the relays to work properly all of these mechanisms need to also be working correctly. The testing of these components including the current transformers, potential transformers and auxiliary circuitry is extremely important. All of these items need to meet manufacturer standards in order for your facility to be properly protected. If they do not meet the standards, PowerCom has trained personnel to fix any problem or replace if needed.
Provide Engineering Studies For Relay Protection
If you are unsure if you facility needs to be protected by relays or if you need to upgrade existing relays. PowerCom also offers engineering studies to analyze your need for the proper protection.
CABLES - LOW, MEDIUM, & HIGH VOLTAGE
Entire Cable Replacement
Cables are the medium that transfers the electricity from the source to your equipment. If the cables fail it could mean an entire shutdown of your facility. PowerCom offers the service of completely replacing the faulty cable with one that exceeds your current needs and removing the old cable from your premises.
If it is determined that a faulty cable is causing an outage in your facility the defective section of the cable can be removed from the cable. A new segment of cable will then be spliced in place of the old one. This will eliminate the fault that was causing your facility downtime.
