TATNEFT is implementing microprocessor-based protection of power transformers and outgoing connections at the substations in its Oil and Gas Production Divisions.
BMRZ microprocessors, with voltages from 0.4 to 111 kV, are designed to perform the functions of relay protection, automation, control and alarm connections.
In addition, the units also provide for broad service capabilities facilitating the work of maintenance personnel. The overhaul is being carried out by Tatneft-Energoservice Management Company.
"Usage of microprocessor devices with modular architecture at the substations of the Company along with modern surface mount technologies ensure high reliability, greater computing power and high-speed response, as well as high precision measurements of electrical parameters and time intervals, which makes it possible to reduce the number of selectivity intervals and increase the terminal sensitivity," the company said.
