Electrical
| Infrared’s ability to
detect faults that may go undetected by the naked eye make it a
lucrative energy saving investment. |
|
| Savings and fault
prevention are real and measurable benefits of thermal imaging. With
fifteen FLIR P65 cameras and 50 trained thermographers on staff, CNA
insurance has made an investment in IR imaging. Now, both customer
and company are reaping the rewards. Infrared’s ability to detect
faults that may go undetected by the naked eye make it a lucrative
investment for preventative maintenance and claim investigation and
a
must-have for any insurance company. |

Connection in a Substation
|
| This thermal image
shows a hot connection (measuring 437°F when viewed with a telescope
lens) in a substation that supplied power to a hospital and nearby
residential neighborhood. The infrared camera pinpointed the anomaly
immediately. An electrical connection had 'blown off' during a
lightning storm and had re-welded itself to the support bracket of
the insulator. |
|
| A wide view of a
substation can quickly show areas where unwanted high resistance
connections exist. Electrical current passing through a resistive
connection produces heat; electrical systems get hot when
connections loosen or corrode and power is not properly transmitted.
No other predictive maintenance technology is as effective for
electrical inspections as IR thermography. |
|
| Excess heat on this
distribution transformer was attributed to internal damage plus low
oil level. |

| This is a computer
chip under test. ThermaCAM imaging radiometers provide instant
identification of a fault. |
