Customer SAVE
REAL Services' customers are engaged in producing manufacturing power, distribution, instrument, and specialty transformers.

REAL Services' LTC3 pioneered a Revolutionary and truly Predictive / Proactive testing methods and data interpretation for determining the operational heath and integrity of Electrical Transmission & Distribution Equipment.  Rather than simply testing Insulating Oil Condition; NOW Transformers, Load Tap Changers (LTC), Oil Filled Circuit Breakers (OCB), Voltage Regulators and other T&D Equipment Condition & Reliability can be monitored, trended and quantified.; provided by REAL Services along with our exclusive SAVE REPORT which provided Return On Investment and Cost Justification for your T&D PM Program.

Electrical Transmission & Distribution

Case Study # 201

These results are obtained, by REAL Services' LTC3 patented testing procedures, from a FIRST time sample tested due to erratic performance.  McGraw Edison Load Tap Changer; C-03422-5-1; is one of two-(2) main LTC of the municipality. Dissolved Gas Analysis (DGA) test results indicates NORMAL operation and to sample next year.

LTC3 condition CRITICAL; Recommendation: Schedule this unit for maintenance action. Specifically, inspect and correct electrical discharge and arching of contact, secure mounting hardware and reduce water contamination to eliminate electrical discharge inside LTC.


Although the equipment particle concentration (EPC) of 269 is well within acceptable limits for this type of equipment, analytical results show a high concentration of Ferrous metal wear particles. These metal particles are from the LTC mounting hardware. The movement of this hardware has resulted in the electrical discharge to surrounding components and contacts. This image displays the Tektites or Spheres (i.e. the Sparks) from electrical discharge.

Note: This was a FIRST time this equipment has been tested.


Upon opening of McGraw Edison Load Tap Changer; C-03422-5-1, contact mounting hardware found to have play and movable by hand. Equipment show signs of electrical discharge and arcing of contacts and internal components.

Secondary Damage, Property Damage and Service Interruption was minimized.  Service Interruption & Downtime was minimized.  Maintenance scheduled and performed during holiday weekend slow period.

LTC3 optimized equipment performance and savings for the utility, customers and investors.


Original Component Savings:                      1,004,500
Secondary Damage Savings:                           24,970
Business Interruption:                                         37,830
Property Damage:                                                   N/A
Rush Shipping Cost Savings:                           15,000
Overtime Repair Savings:                                    7,195                                     Total SAVINGS:   $ 1,089,495

Now available one simple test to determine the condition of T&D Equipment Reliability based on the that equipment.

 - NO special sampling containers or expensive test.

 - One-(1) test to determines over 30 problems such as Coking, Filming, Electrical Shorts and even the break down of Paper Insulation & Plastic Insulation.


....       Raising T&D Equipment Condition  Testing to a Higher Power.
