  Sigma Relays are switching equipment that can perform electrical circuit control. The biggest reason why relays working with an electromechanical system are used in electrical and electronic circuits is that they can control high currents with low currents. Relays are generally used in control circuits. • Level Control Relay: In monitoring environments such as tanks, water tanks and wells containing conductive liquids, • 1-Phase Voltage Relay: For protection of devices and motors in single-phase systems from over and under voltages • 3-Phase Voltage Relay: Protecting devices and motors in 3-phase systems from over and under voltage, • Asymmetrical Cycle Time Relay: General room ventilation, periodic dehumidification, lighting control, circulation pumps, signage, etc. in areas, • Star-Delta Delayed Time Relay: Providing the required time interval during the transition from star connection to delta connection, • Single Function Time Relay: In applications where function and time requirements are known • Multi-Functional Time Relay: Used in electrical devices, lighting control, heating, motors, pumps and fans (10 functions, 10 time intervals, Multi-voltage).  

  Sigma new generation Reactive Power Control Relays are a technological product that activates and deactivates capacitors and shunt reactors in order to balance active power and reactive power ratios in line with the needs of the facility. Sigma Reactive Power Control Relays are offered to the user with features that will provide a complete and comprehensive solution to all kinds of compensation needs in balanced or unbalanced loads, suddenly changing or normally changing loads, in facilities where SVC must be used, in facilities operating outside inductive and capacitive limits.  

  Sigma SVC system is a new system developed because classical compensation systems made with capacitor stages cannot fully respond to today's businesses where loads with capacitive characteristics and rapidly changing reactive loads are widespread.  

  Shunt reactors are compensation elements that are used in compensation systems to balance the capacitive load by creating an inductive effect by being activated by the reactive power control relay in case the capacitive load increases. The capacitive effect caused by long underground power lines, UPSs, computers, electronic ballasts and LED lighting is compensated and balanced by the use of shunt reactors. Sigma Shunt Reactors are produced from 0.25 kVAr to 10 kVAr in single-phase stages, and from 0.25 kVAr to 50 kVAr in three-phase stages.  

  Capacitors used for compensation are connected in parallel to the network in businesses with inductive reactive power character where loads such as motors, transformers and coils predominate, in order to prevent inductive reactive power withdrawal from the network and to avoid possible penal situations that may arise due to reactive penalty rates. These capacitors are designed and implemented in a way that they can compensate for the reactive power of the facility in any case, with various fixed or automatic applications depending on the load situation.  

  Sigma Compensation Contactors are produced specifically for compensation systems. The excess current drawn by the capacitors when they are first switched on is reduced by current limiting resistors before it reaches the main contacts of the contactor. As a result, the contactor contacts are not exposed to the high currents that occur during the activation of the compensation system and the contact life of the contactor is extended, thus mechanical and electrical stresses are prevented. In addition, thanks to the special tubing with V0 non-flammability used on the outer surface of the current limiting resistors, it does not allow any fire risk during the passage of high currents.

Thanks to the double indicator structure, it is easily observed that the NH fuse is disabled, thus providing less downtime and less cost.
