The Syntron automatic power factor control relay type 1143 is specially designed to provide accurate and reliable control of power factor of an electrical installation 1143 has micro controller technology. This is a Syntron exclusive trademarked as COSROBOTTM. COSROBOTTM technology evolved at Syntron specifically for use in APFCRs where the problems of electrical noise, transients etc. are accentuated, and normal microprocessor technology fails under such conditions. COSROBOTTM 1143 is now more reliable and easier to troubleshoot. Operationally the COSROBOTTM APFCR 1143 is identical to the previous IC based version for compatibility with older panels. Some features, not available with IC based APFCRs, are provided additionally in 1143:

1 Some users, with peculiarly configured systems used to find it difficult to use Syntron automatic power factor control relay type 1143 with the Low Current Cutout set at 20%. Low Current Cutout is now reduced to 5% to accommodate such systems.

2 Some users demand timing between stages different from our standard. This modification is needed for thyristor controlled capacitors, windmills etc. This timing can now be factory set at a value from 0.2 seconds to 25 seconds.

3 The First In First Out sequence now comes with built in software timers - one for each stage - so that the APFCR waits only if the next needed capacitor is still discharging, otherwise it is switched on immediately.

4 Any other sequence such as 1+2+2+….., 1+2+4+8+…etc. are also given,factory programmed as per order. 5 There are two alarm conditions that are directly displayed Current Low (the display reads 1uuu) and Wrong Wiring (the display reads 2uuu). This condition is detected if your wiring of the APFCR is wrong, and will persist till you correctly wire the APFCR into the system.

Function: When switched on first, the 1179 measures it’s environment, and tells the user if there is anything wrong. Thus if the load current is extremely low (below about 0.5%) it gives a different display, if your connections are not correct, it gives an alarm, etc. Each stage of the 1179 has a corresponding software timer in memory. Thus whenever a stage is switched off the times begins counting 60 seconds, 1179 then does not switch it on even if needed, because that capacitor is charged, and re-switching it would ruin it on transients. 1179 then re-calulates and switches on other combination that will do the job. However the capacitor is used immediately after the timing is over. Manual Control of the 1179 is also unique.

Power Factor is an important parameter needing control. The Syntron automatic power factor control relay type 1107 is specifically designed to control the power factor of an installation accurately and reliably. Introduced first in 1982, the automatic power factor control relay type 1107 has undergone countless refinements and improvement to make it the most sought after APFCR in India. The leaflet reflects all the changes, refinements and additions made in the line. The major additions are: The original 1107 had an analog power factor meter, some users demand a digital power factor meter thinking that it would be more accurate. Actually the PF meters normally provided are 2 ½ digit type, the resolution of which is worse. Accuracy may be the same. We therefore designed in a four digit power factor meter the accuracy of which is the same as analog and resolution is ten times better than the two and a half digit versions. The meter provided on the 1107 is also far more stable to provide meaningful readings.

• Built in test facility.

Function: The APFCR controls the power factor of the installation by giving signals to switch on or off power factor correction capacitors. It should be noted that this is only a Relay constituting the so to say 'brain' of the system and it cannot switch the capacitors directly but need intermediate contractors of appropriate ratings. The APFCR has a built in power factor transducer which measures the power factor of the installation and converts it to a DC voltage of appropriate polarity. This is compared with a reference voltage which can be set by means of a knob calibrated in term of power factor. When the power factor falls below setting, the APFCR switches on the capacitors one by one in sequence, which can be either First In First Out (FIFO) or First in Last Out (FILO). In either case the capacitors of all stages must all be of same rating. The Relay switches them on in linear sequence Facilities: Power Factor Meter : Four Digit Digital Meter. Please refer description above. PF Setting Dial: The required PF is to be set on this dial calibrated from 0.75 lag to .99 lead Dead Band Knob: This setting determines the range of phase angle over which the Relay will not respond. Dead Band is necessary to prevent overcorrection and hunting. Undercurrent Blocking: When the load is low the effect of the capacitors is more pronounced and may lead to hunting. Undercurrent Blocking shuts down the Relay when the load is too low, and switches off all the capacitors one by one in sequence. Auto/Manual Facility : The system may be operated manually from the Relay by this control. Special Timing Sequence: The APFCR has a built in logic timer which inhibits operation for a fixed delay of 65 seconds for LT Relays (and 310 seconds for HT application Relays) whenever the following changeover occur: • Changeover from Auto to Manual and vice versa. • Changeover from capacitor off to capacitor on signal. This delay ensures that the capacitors are fully discharged before they are re switched in. This avoids transient and damage to capacitors. Indication : The APFCR has solid state indication lamps (LEDs) for every one of the function the operator should know about : Auto, Manual, Low PF, High PF, Timer, Amps OK, Test (to indicate that the Relay is in TEST Mode.) and for each capacitor switching stage.
