Our Experienced Team Has Installed Thousands of Transformers and Kept Them In Service, Delivering The Reliable Power You Need

You’ve purchased a new transformer, but there’s SOME ASSEMBLY REQUIRED! TPS has the capability and equipment to completely assemble and install your transformers. We install transformer of all capacities ranging for 50KVA to 100MVA.TPS can also disassemble units that may need to be moved.
We can start with receiving inspection at the rail siding, port of entry, substation site or wherever the unit is located, and then assemble all parts that were removed for shipment to make the transformer operational. If the unit was shipped oil-filled and it is necessary to lower the oil level to install bushings or other parts, TPS can get it done.

TPS oil tank trucks can be summoned to the site for oil storage or hauling, and we can bring in one of our many oil-processing rigs. Using your specifications, the transformer supplier’s specifications or ours, TPS can vacuum degasify and prepare new oil for installation, pull vacuum on the transformer and professionally complete the vacuum oil-filling process.

A wide range of tests can also be performed to verify that your transformer is ready for service:

Omicron Power Factor Test of Windings
Omicron Power Factor Test of Bushings
Omicron Surge Arrester Test
Core Resistance (Megger)
TTR (Transformer Turns Ratio)
Winding Insulation Resistance

Transformer Life Assessment

All transformers require maintenance and repairs to ensure that they are functioning up to industry and manufacturer’s standards. The likelihood of repairs and maintenance increases as the transformer ages and becomes more susceptible to wear and tear. TPS’s goal when dealing with transformers is to ensure safe and reliable transformer operations by tackling maintenance and repair problems at its core. We do not simply fix the symptoms, we try to address the causes with state of the art testing equipment and NETA certified Technicians and Engineers. Every industrial company possesses large power transformers; some even possess transformers that date back over half a century. If you feel as though it’s time for maintenance and repairs for preventative measures or to fix an existing problem, TPS is the company for you.

TPS’s transformer evaluations and analysis include the following services:

On Site inspection of transformers
NETA standardized testing for the transformers

Types of Transformer Tests

The purpose of a transformer Ratio Test is to specify the specific voltage at the LV (low voltage) terminal and the HV (high voltage) terminal in order to calculate the number of turns within the coils of the transformer.

Make sure that the tap change for the transformer is at the lowest setting and that the low voltage terminals are open
3 phase 415 V should then be applied across the high voltage terminals
Measure the voltages across each phase on HV and the induced voltage at LV at the concurrently
Raise the tap changer of the transformer and repeat the measuring process in steps 1-3

Dielectric Tests: For the test, higher voltage is induced across the transformer to ensure that the transformer can handle the potential difference. The purpose of a dielectric test is to ensure that the transformer and insulation structure are functioning at manufacture standards even when a larger potential difference is induced.

Hypot Test: The purpose of the hypot test is to ensure that leads and ground clearances for insulation structures are up to standard. Tests are specified based on ANSI and usually done in one minute intervals (visit our hypot test site for more information)

Induced Voltage Test: Purpose of the induced voltage test is to find variations in test frequencies.

Sound LEVEL TEST: Under OSHA standards, employees cannot be exposed to sounds than 90 decibels without proper PPE. Sound level for transformers are recorded at various heights around the transformer. Low levels of noise in the background are necessary to ensure accurate measurements.

Temperature Rise Tests: Temperature Rise Tests are used to determine the amount of time needed for a transformer to cool and is done to ensure safety for employees working with transformers

This page gives very brief details about transformer tests. For more information, refer to the NETA Standards for Transformer Testing or contact TPS

Transformer Oil Testing and Oil Analysis

As a result of high operational temperatures, chemical interactions within the windings, and interactions with solid contaminants, the original properties of the oil in transformer changes gradually as the transformer ages. The result of these interactions can be costly and hazardous for transformer itself and the substation that it’s connected to. The oil needs to be systematically tested and maintained to ensure the highest quality standards are met.

Oil Testing Packages Offered at TPS

Oil testing packages offered at TPS include Fault Determination, Routine Tests, Transformer Signature, and Pre-Commissioning

Fault Determination Test Packages serve to specify and determine damages and problems with transformers. The oil tests include dissolved gas analysis, water content, contaminants in oil, and Furan content.

Routine Test Packages are a preventative measure used to maintain the health of the transformer. Thorough and scheduled maintenance helps prevent degradation of transformers and ensures proper operation. These tests include dissolved gas analysis that come from the transformer oils, furan content, resistivity and acidity tests, flash point Tests, sludge, and dielectric tests.

Transformer Signature Packages help identify the time-zero condition for each specific transformer. These tests include but are not limited to water content tests, furan contents test, Power Factor at 90 °C and 27 °C.

Pre Commissioning Packages are meant to ensure that new transformers are up to standard before they are installed into your particular power system. The recommended tests in this package are DGA (dissolved gas analysis), water content, oil contaminants, Furan Content, and Power Factor at 90 °C and 27 °C.
