A scientific-technical ession on protective relaying, organized by the
?OP 'Mini_try of the Electrical indu try USSR) and the Cor'kiy Division of
VNITOE +A1_ -.Union Scientific and Technical Society of Power Engineers), was
held in Chehokeary in October 1950 Pre-ent were 120 delegates from electric
power ev:tem:, cientific-'(esearch andapl nnicn~gfo matheate~hnichigherinistaa-
tional io.s`.= u?e , pianIs of the MEP,
Lion of the ME= (MinlEtry of Electric Power Stations USSR) and the MEP.
The eeseion wa; opened by A. 1. Yakunin, director of an MEP plant.
ted N. N.
Nikitin, ecretary of the Chuvash Oblast Committee of +he.V1( ) lan
greeting for the oblast committee and expre"eed his confidence thatnthe,set-
Pion would help plants to improve the quality of their relay equipment
solution of important tasks in relay construction with the develop-
ment of the new, gigantic electric power et.a+. ions.
In his report, Engineer A. V. Buyvolov of an MEP plant pointed out that
there has recently been a considerable expansion in the nomenclature of relays
ooper-
produced. by the Soviet electric industry, and that due,tot the creativeEcooper-
ation between the plants and the laboratories of TEP (State
Power Planning) and TSNIEL (Central Scientific -Research Electrical Engineering
Laboratory) of NEST the relay-protection equipment produced is better than
similar equipment built by foreign enterprises.
Engineer M. P Tsfasman of an MEP plant emphasized the improvement in the
quality of relay equipment, and pointed. out increased cooperation between
plants and the consumer organizations would also bring further improvements in
quality.
Engineer le. D. Zeylidzon (Technical Administration of MES) submitted a
report on "Operating Experience With Relays and Demands Made by Electric Power
Enterprises on the Electrical Industry In the Field of Relay Construction."

characteristics of an lectrical automatic repeated reclosi.ng unit developed
by the TsN1EL and accepted for production by the electrical industry. He also
emphasized the high efficiency of phase-by-phase automatic repeated reclosing
in electric power systemsEngineer P. K. Feyst, of TsNIEL, presented a paper
on a ;elective device developed for phase-by-phase automatic repeated reclos-
ing with balanced relays hating minimum total resistance.
Candidate in Technical Science A. M. Bresler of an MEP plant spoke on
"Distance-Relay Protection of Transmission Lines" and reported on distance
relays already in use as. Relay PZ-151 for lines with low ground currents, and
Relay PZ-155 for lines with sizable ground currents. The development of a
distance-protection circuit against single-phase short circuits in systems
with a floating nsutra] has been completed.
In his paper, Professor G. I. Atabekov, Doctor of Technical Science of
'.PsN1EL, suggested distance relay protection for medium-haul lines against in-
terphase short circuits by the use of a quadruple-relay system and protection

Cand1-date in Technical Science T. A. Syromyatnikov (Technical Administra-

relay protection and automatic devices, He pointed out that automatic field
s,rength control should be introduced in all generators, and all suspension
liner should be equipped with automatic repeated reclo:ing. Further, Syromy-
athikov stated that automatic introduction of reserves for the internal needs
of power Cations should be used more widely as protection based on the through
ac in !high-voltage systems The development of gigantic hydroelectric power
stations will require great collaborative efforts on the part of scientific-
recearch, planning and operational organizations, and the plants of the MEP.
Resolutions adopted by the session dealt with methods for further improve-
ment of relay equipment, and recommendation- were made for a broadening of the
nomenclature of relays and complete protective units in production.
