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. |
