General

Electricity networks are gradually overloaded as a result of increasing use and demand of emerging technologies In all sectors. While the compensation becomes a nightmare for the companies having unstable load, even the companies having stable load in the past have now difficulties to provide reactive compensation. Therefore, the period of reactive power relays measured by single-phase will be over in the close future. KAEL Elektronik has incorporated a brand-new device to the electricity sector having much more steps, quite good equipped in terms of function means and software with improved running algorithms, by combining the achievements and experiences coming along with VARkombi-12-PC-TFT-OG regarding the reactive power compensation. Facilities are provided to the users with many graphics and animation by using large 3.2 " color LCD screen on the device. Moreover, the microprocessor in the device is running very fast and an operating system is used. This provides to reach all transactions running simultaneously.

In case the blue led on the lower left corner of the front panel of the device flashes, this means it is close to the value of penalty % and authorized persons should be informed as soon as possible. This is also useful in terms of taking the attention of the end-user in case of penalty who does not know this functional issue.

■ The connections of the device should be made while the system is energy-free.

■ VARkombi-12-PC-TFT-OG should be connected as shown in the connection diagram.

■ Three phase and neutral connections should be made to the voltage input. Phase should not be given instead of neutral. Otherwise the device can be damaged.

■ Current connections should be made as to match the same phase with the same current transformer. Scheme should be followed.

■ The value of the selected current transformers should not be under the real load values but should be X/5 amper. It is also advised to choose 0.5 class.

■ Connect the “C1, C2, C3” common phase inputs to the same phase with FF type fuses seperately. Select the fuses to be used according to the specified current value.

■ The outputs of the steps are not needed to be made in any order. However, the first 6 steps can consist of triple-phase capacitor groups. It is recomended to connect single-phase capacitors to the second and third 6 steps and, to connect capacitors or reactors to the third 6 steps in terms of accepting the statements in this manual.

■ Make the connections to the generator if it is used.

■ Make RS485 connection. (Not applicable in VARkombi-12-TFT-OG)

■ Do not energize the device without ensuring the connections checked by measurement instruments.

Device requires to enter the number of steps. In this case, the screen on the right side will be displayed. The number of step is set-up to the required value by the direction keys and “Apply” is selected. In case “Okay” key is pressed, saves the change. Or, in case no key is pressed, when the time is over on the screen, it switches to the section in which the current transformer ratio is inserted by taking 12 steps in the memory.

The line on which the blue bar locates, is setup to the required value by using the direction keys and switch to the next side by pressing the left direction key. Inserting the complete primary value, “Apply” key is pressed. In case of pressing “Okay” key, the change is saved.

The device automatically switches to the internalization of current polarity directions mode. In this case, it is required to draw enough current from each phase. If enough current can not be drawn from any phase, the device warns as “current flow directions not detected” and shows the phase or phases which are not internalized by ??? marks. When the total of current polarity directions are internalized, the device switches to the automatic capacitor power internalization mode. P.S.: There is no need to press on the main screen key normally.

2. Step : Number of Steps

3. Step : Current Transformer Ratio

4. Step : Determine of Current Transformer Directions

This is the enterance section of the value of decharge period (sec) holded for preventing the capacitor to activate again without decharging in the same step in case of requirement, after release of the activated step. The value is setup to the required step starting from the digit under which the blue line is, by using up and down keys. Then left key is pressed and the blue line moves next to left digit. All the values are entered in the same way by using up and down keys. Press “Apply” key inorder to take the period of step activating into memory. “Save changes” message will appear on the screen. When “Okay” key is pressed, the value is taken into memory. Period of activating line is subjected to a function with the % value obtained from the ratio of energies. In case % value is getting close to the inductive penalty line value, the time is reduced automatically by the device. If necessasy, compensation speeds up; and if not, it slows down by means of dynamic control of step activating, and continously do not make fast moves unnecessarily. P.S.: Step activating time counts only for capacitor released newly. If necessary and a close solution is found in another step, device activates the other option on time and the compensation is not delayed. If it' s not required the device to respond so quickly, holding period between the steps can be extended to delay receiving process by increasing the value of ΔT on switching time described in the next chapter.

P.S.3: In case of selecting the switch on time less than min.step time, device accepts the switch on time as constant time value.

1 7 10 1

Other Relays : They proceed the step activating transaction with constant time adjusted. If the time is not over, they will wait for the deadline. This causes delays in the compensation. VARkombi-12-PC-TFT-OG : It collects the energies (ind., cap., active) consumed. Step activating and de-activating periods are decreased or increased automatically by the device according to the consumed enerygy. P.S.: The energies consumed in VARkombi-12-PC-TFT-OG and the % values are calculated separately for each phase. Therefore, step activating and de-activating periods of each phase can vary. For instance, while the step activating time for R-phase down to 2 seconds, the one for Sphase can be 7 sec. VARkombi-12-PC-TFT-OG analyze the system phase by phase and set-up the compensation rate for each phase seperately. The most simple explanation regarding the ratio of energy of step activating period has been given below. In fact the function consists of much more complicated and an array of fuzzy logic. Step subperiod (min) determines the lowest time value of level activating time which can be reduced by the device. This parameter can be specified by the user.

This is the section in which the step parameters are deleted one by one, or all. In case the reactive load is changed in any step, the power of that step must be deleted to let the device internalize the the power of new step. The device fowards the user continuously by sub-command screen. Moving onto the step of which power required to be deleted, the up or down key is pressed. The line is in red colour in the meantime. In case of deleting only that step, “Delete” key is pressed; in case of deleting all steps (if a device used in somewhere else is connected to a new plant), “Delete All” key is pressed. If “Delete” key is pressed, “Step Delete?” warning appears on the screen. When “Okay” key is pressed, the power of that step would be deleted. The device will automatically try to internalize the power of that step again. You can exit the menu by “Exit” key. In case “Delete All?” key is pressed, “Steps Delete?” warning appears on the screen. When “Okay” key is pressed, the power of all steps would be deleted.

It' a useful function in terms of warning the user. First, it' s better to clarify some definitions step alteration control page: Old value : The first internalized power of step. New value: The power alterated minimum ± 15% with respect to the past value. This page has been designed to identify and enter the real value of steps whose powers are not internalized, even though the powers are alterated over time or replaced with the past one by the user. In case the new value of any step is alterated ± 50% with respect to the first value, the device warns the user as “Change in the power of capacitor”. If the capacitor in which alert is given has really alterated, then the new value should be loaded instead of the past one. The alteration in step power appears on the screen as a warning In case internalization of step power is activated, the device controls the capacitor power at every step activation and deactivation process. In case of a change in the power, the device determines it and continue to compensate with the final value internalized. If “Off” is selected, the device internalize capacitor powers only at the first activation. It determines the alteration, however continues the compensation with the first internalized values.

The device directs the user with sub-command screen continuously. The red frame is moved on the step whose power decreased (box in blue colour) by using up and down keys and “Select” key is pressed. Sub-command screen is alterated. In case of which value will be used, past or new value key is pressed and then load key is presse. “Load selected value to step?” question appears on the screen. If “Yes” key is pressed, load will be completed.
