For any dielectric coolant (petroleum, synthetic or biodegradable) insulating fluid, the conversion of high-boiling residual liquid, under the catalyst of heat and pressure, to higher-value naphthas, and other light products. The process produces as a by-product a dry, predominantly carbonaceous residue called coke. Accumulation of coking reduces the electrical conductivity and increases the probability of aberrant electrical discharge in T&D equipment. The coking level is a good indicator of equipment efficiency and should be monitored on a regular basis for possible maintenance action.
Coking builds up continuously until it reaches an unacceptable level, that level depends on the type of electrical T&D equipment, operating conditions and the dielectric fluid. Coke remains suspended in the oil as they are too small to be removed by the filter. Elevated coke levels tend to precipitate onto contact surfaces and reduce the conductivity, hence, increases the resistant properties of these surfaces, resulting in greater power draw across the contacts or other conducting surfaces.
To-day, testing and analysis programs utilize modern technology and laboratory instruments to determine equipment condition and lubricant serviceability. REAL Services uses state-of-the-art equipment and techniques to provide the best analysis possible. The service will provide the user with invaluable information leading to greater equipment reliability.
REAL Services LTC3 patented technology allows for the quantifying or the coking in specific terms of parts per million (ppm).
