CALIBRATION LABORATORY

RISAS new facility includes a state of the art calibration laboratory that utilizes the latest technologies and calibration equipment side by side with very superior quality systems that meet the exacting and stringent requirements of government and commercial agencies to assure operation with top, precise, and reliable functionality.

The calibration capabilities cover various electrical, electronic and mechanical instruments.

Calibration of your instrument is accomplished by comparison to standard maintained by RISAS calibration laboratory and using standards that are directly/indirectly traceable to the National Physical laboratory (UK) and National Institute of Standards and Technology (U.S) within the limitation of their laboratories services, or have been derived from accepted values of physical constants, or by the ratio type of self-calibration techniques.
OIL LABORATORY

Transformers are one of the most expensive components of your transmission and distribution assets. With the skyrocketing cost of materials it is more important now than ever to protect your infrastructure. 85% of oil filled transformer failures are caused by moisture in the oil. Most of these failures could have been avoided by an inexpensive testing regiment. The total cost of a transformer failure typically costs between 5 and 20 times the cost of the transformer.

RISAS is equipped with the latest technologies utilizing automatic laboratory oil test sets to perform accurate breakdown voltage tests, transformer insulating oil sample analysis and standard oil quality tests comprising:
