Active Harmonic Filter

The structure consisting of a semiconductor-based rectifier and battery groups that meet the DC energy needs of the equipment in transformers or distribution centers, are constantly connected to the direct current loads here, have constant voltage, and are automatically regulated according to the change in network voltage, is called a battery rectifier group. Battery rectifier groups are used to control the motor and on-off coils, lighting lamps, signal lamps, etc. of the medium voltage cells in the substation where they are located. feeds the equipment. While the mains supply voltage is 220 VAC, the output voltage of the rectifier can be 24 VDC, 48 VDC or 110 VDC.

Harmonic filter reactor is used to control and filter harmonic distortions in electrical systems. Harmonic distortions that occur in electrical systems are electrical signals that contain unwanted voltage and current waves at incorrect frequencies.
Harmonic filter reactors help control harmonic distortions by using them in industrial facilities and energy distribution systems. This allows energy systems to operate more efficiently and transmit electrical energy without damaging other devices.

Fault indicator mechanism is a mechanism that detects faults occurring in electrical or electronic systems and notifies the user.
The working principle of the fault indicator mechanism is as follows;
It measures the phase currents from three current transformers connected to underground network cables and calculates the ground current. If the measured phase current exceeds the threshold value for a set time, a fault is detected. When a fault is detected, the screen shows which phases or ground faults occur. In all fault cases, the fault indicator flashes and the contacts close. If the fault goes away before the automatic reset time expires and this situation lasts for 3 seconds, it returns to normal state.

Shunt reactor is an inductance (L) element used in electrical circuits. It usually has a parallel connection and the switchreactor is used to correct the power factor or reduce harmonics in electrical systems. The working principle is that the inductance delays the electric current and thus improves the power factor. This helps the reactor to absorb harmonic currents in the circuit and thus protect the electrical system from undesirable effects.

This is a 6-channel signal warning relay combination. It is designed to alert the user to system malfunctions, typically in distribution centers, using its built-in signal lights and a horn output. This allows for quicker response to malfunctions.

Active Harmonic Filters (AHFs) are advanced power quality solutions used to eliminate harmonic distortions caused by nonlinear loads in modern electrical systems. Harmonics can cause unwanted fluctuations in electrical current and voltage, negatively impacting system performance and equipment life. Active Harmonic Filters detect these disruptive components in real time and remove them from the system by generating counter-phase currents, thus improving energy quality and ensuring more efficient and secure operation of the electrical infrastructure.

The SVG (Static Var Generator) works to correct voltage imbalances in the grid, improve the power factor, and balance reactive power. Instead of traditional methods like capacitors or reactors, it uses fast-response IGBT-based technology. Thanks to its modular structure, compensation power can be easily increased by integrating multiple units in parallel.
