OVR    220 - 300V    TE 201                   OVR    400 - 500 V    211

        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 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. Both under & over & voltage are settable. Time is fixed at 3-5 sec Hysterisis of 5-15 V for transient protection is provided.

TIMERS AC - DC

 

AC 230 V      DC 12 V OR 24 V           TE 100

ON delay TE 100       Initially off, after set time timer on - contact change

Off delay TE 130       Initially on, after set time timer turns off-contact change.

Stop timer TE 130     Initially on, after set time off. For pulling stop solenoid of engine for 5-30s

Time delay is as per order which are   -    1-10s   10-100s     6-60s    0.3-3min    1-10min

All contact are 5A potential free. Any of these times can be specified at order.

OVER CURRENT RELAY

EARTH FAULT RELAY

EARTH LEAKAGE RELAY

 

Over Current                  0.5 - 5 A        TE 510

Earth Fault                    0.2 - 2 A        TE 520

Earth Leakage Relay     50 - 500 Ma   TE 560

Teknika Single element over current / earth fault / earth leakage relays are ideal for sensing current faults in any one phase or earth for protection of AC machines. Transformers, generators etc. The resultant current measured is digitlly compared to a settable reference. In case of trip condition trip contacts changeover after a settable time of 1-10 sec. This can be used to trip the breaker. Time must be set according to system requirements. Two changeover contacts are available.

3 - Element Over Current      TE 530

3 - Element 2OC / 1EF           TE 531

 

Earth Fault                  0.2 -2 A       

Over Current               0.5 - 5 A       

TE 530 series of Over current relays are ideal for sensing over current faults in any or all phases for protection of AC Machines, Transformers, Generators etc. The relay monitors the current passing in any feeder secondary. The resultant current is digitally compared to the settable reference. Each phase has its independent setting. Timer starts on trip condition and is common for all three phases - a changeover occurs. Time must be set according to the system requirements. Two sets of changeover contact are available - common for all.

REVERSE POWER RELAY        TE 800

 

RYB SENSING      Reverse Power     -      6 - 10 %

TE 800 series RPR relay monitors the power flowing in the phases. The direction of the power is checked. The relay monitors current flowing in the B phase. This current is squared with the voltage in RY phase and motoring condition detected. Power sensed is compared to a reference and a timer is triggered above limit. Timer can be set 0-10 sec. Contacts changeover occurs on time out and an LED indication signals closure.

FREQUENCY RELAY        TE 700

SPEED RELAY                 TE 710

 

Over Frequency           50 - 55 Hz

Over Speed                 1500 - 1650 rpm

TE 700 series frequency relays are used for protection of sensitive equipment due to under or over frequency when the equipment is being supplied from a source whose frequency may be erratic. Can be used for tripping in case frequency goes above limit. A lower or higher than limit condition if persisting for more than 1 or 2 sec a contact changeover occurs and an LED on facia glows to indicate a trip condition. This can be used to trip the breaker / supply. Two sets of changeover contacts are available. The relay is auto reset type.
