MOTOR (FAZ) KORUMA ve FAZ SIRASI RÖLELERÝ
MKC-03A, MKC-03L, MKC-04A
Genel
Sanayi tesislerimizde yayg›n olarak kullan›lan elektrik motorlar›n›n iki faza kalarak
aþ›r› ›s›nmas› ve yanmas› s›kça karþ›laþ›lan ar›za kaynaklar›ndan biridir. Motor
korumas›nda s›kça kullan›lan “termikmanyetik röle” gerek elektro-mekanik yap›s›,
gerekse demeraj ak›m›n›n karþ›lanabilmesi için ak›m ayar›n›n yüksek tutulmas›
nedeniyle, koruma iþleminde yetersiz kalmaktad›r.
Bu olumsuz etkileri ortadan kald›racak þekilde tasarlanm›þ olan “nötr’lü MKC 03A
ve “nötr’süz MKC-04A” Motor Koruma Röleleri aþa¤›daki koruma fonksiyonlar›n›
yerine getirir.

1- Gerilim Dengesizli¤i (Ayarlanamaz)
C1
Faz-Nötr aras› gerilim dengesizli¤i (sabit) %15’tan fazla oldu¤u anda ç›k›þ rölesi
motoru devreden ç›kart›r. Özel istek üzerine %5-%15 arasý sabit gerilim dengesizliðine
sahip cihazlar üretilebilir.
Üç fazlý sistemlerde gerilim dengesizliði (asimetri);
Yüklerin fazlara dengesiz baðlanmasý sonucu oluþabileceði gibi,
Üç fazlý motorlarda fazlardan birinin kesilmesi durumunda da oluþur. Bu durumda
kesilen faza ait motor sargý ucunda, motorun diðer sargýlarý üzerinden indüklenerek
dönen gerilim görülür. Bu gerilim deðeri motorun cinsine ve yük durumuna göre
deðiþir.

2. Faz s›ras›
Faz s›ras›n›n ters oldu¤u durumlarda (yani L1, L2, L3, saat yönünde de¤il ise) motor
devreye al›nmaz. Herhangi bir nedenle faz s›ras› bozulursa motor gecikmesiz olarak

PHASE FAILURE and PHASE SEQUENCE DEVICES

Connection Diagrams PK-25
General
One of the common faults faced in industrial plants is over-heating and burning of
3 phase motors due to the phase failure. “Thermic-magnetic device” which is an
essential element in motor protection is generally too slow due to both its electromechanical structure and the use of high current setting range to assure demarrage
without tripping. Being designed to eliminate the above disadvantages, MKC-03A
(with neutral connection ), MKC-04A (without neutral connection) Phase Failure
Devices react within 0.2 seconds (fixed) against the following faults and take the
motor out of service.

1. Voltage Unbalance (Not Adjustable)
MK-04 includes no neutral connection.
When the neutral-phase voltage unbalance is greater than 40% (fixed), the output
relay is activated and switched OFF the motor. Devices that have fixed voltage
unbalance between 5%-15% can be producted for special order.
Unbalanced voltage may occured when;
The mains are loaded with unbalanced distribution,
One of the 3-phase of motor has lost. In this case, some amount of voltage which
produced by other phases will be inducted on the lost phase. Amount of this value
depends on both the motor type and amount of load.
Output relay is activated when a phase has lost or an unbalanced phase-neutral
value, which is occured with any reason, is smaller than the Asymetrical value which
is defined for the device. If this unbalanced voltage exceeds the adjusted Asymetrical
value, output will release itself and motor will be Switched-off.
In Applications; a proper device must be used regarding to the inducted voltage
value in two-phase which are remained after the other one has lost.
