Teknika voltage relays are used in protection of gensets, motors, pumps, transformers, shunt caps etc from damage due to transient blackouts, brownouts & for auto start stop of AMF panels. A low or high in all or any phase generates a changeover signal. Two potential free c/o contacts are given for breaker tripping. Relay is auto reset. Both time and voltage are settable Hysterisis of 5-15 V for transient protection is provided.
Teknika autosynchroniser relay is used for paralleling of gensets by matching voltage, frequency, phase angle and zero crossover, internal settings for speed of closure (fst, medium, slow) and breaker close timings. Relay gives a breaker close signal and locks itself out preventing further commands. Raise / lower signals for frequency and voltage can be used to increase
and decrease genset speed and AVR outpur voltage.
Teknika 4 fault annunciators are digital units with front end lit be LED's. Applications are in monitoring faults conditions in any process, equipments etc. A potential free fault condition triggers a buzzer, trip contact and a contact for hooter if external hooter is desired. Also the corresponding window flashes, two changeover contacts trip to signal trip indication and an internal
buzzer beeps to signal fault condition.
Teknika UO Voltage relaysare used in protection of gensets, motors, pumps, transforers, shunt caps etc. from damage due to transient blackouts, brownouts & for auto start stop o AMF panels a low or high in all or any phase generates a changeover signal. Two potential free c/o contacts are given for breaker tripping - Relay is auto reset. Time is fixed at 3-5 sec Hysterisis of 5-15 V for transient protection is provided.
Cyclic timers are used in cyclic operation of two motors where alternate pumping is required. Time can be ordered as per requirement. Standard times are 0.2 - 2 hrs seperate changeover contacts for ON and OFF times. Star delta timers are used for starting star delta motors. At power on star connection is made for selectable time after which delta connection is made.The relay resets automatically and remains off when voltage is low, zero.
