Intro: Separate Hydrogen and Oxygen from Water Through ElectrolysisElectrolysis a method of separating elements by pushing an electric current through a compound. Step 1: Electrolysis of Water - An ExplanationThis section is an explanation of the electrolysis of water, feel free to skip it if you don't find it interesting. Today, if you look around, virtually everything you see is powered by electricity in some form or the other. DC: Solar cells, fuel cells, and thermocouples are the main sources for the production of DC. Iam very interested in wind energy, on top of that iam expert of this clean and safe renewable energy. I lack something in my knowledge, despite my masters of science (UNIVERSITY OF DAR ES SALAAM, TANZANIA) in Physics pertaining to wind energy. Buzzle will explain the difference between the 2 forms of current - alternating current and direct current.
AC or DC?It is believed that DC is less hazardous than AC, but there is no definitive proof about it. If you have heard the names AC and DC for the first time, then this Buzzle article will be very helpful in introducing the basic concepts about these power sources.What is AC?An alternating current can be defined as a flow of electric charge that changes its direction at regular intervals. LED and LCD TVs also run on DC that is converting from the usual AC power source.Why is AC used for power transmission?It is cheaper and easier to produce AC.
Power stations and transformers reduce the magnitude of this voltage to a usable level (110 or 230 V) before transferring it to our homes.
There is a misunderstanding that coming in contact with high voltage AC is more lethal than low voltage DC. Actually, it's not about the voltage, it is about the amount of current that passes through the human body.So, don't mess with electricity as it can prove hazardous. Measurements of these switching overvoltages are performed in the air-insulated substation HPP Grabovica on River Neretva, which is an important object for operation of electric power system of Bosnia and Herzegovina.Investigations of operating of air disconnector type Centre-Break were performed in order to determine switching overvoltage levels that can lead to relay tripping in HPP Grabovica. During operations of disconnector (synchronization or disconnecting of generator from network) malfunctions of signalling devices and burning of supply units of protection relays were appeared. Marine vehicles, spacecrafts, and military equipment sometimes use AC with a frequency of 400 Hz. Don't insert your finger or objects inside power sockets or gadgets and high power equipment. When these ions come into contact with their respective electrodes they either gain or lose electrons depending on there ionic charge. However, for most of the time, including domestic use, the frequency of AC is fixed at 50 or 60 Hz. INTRODUCTION Switching operation in power stations and substations, highvoltage faults and lightning cause high levels of high frequency overvoltages that can be coupled with low voltage secondary circuits and electronic equipment unless they are suitably protected. There have been reports of 50%-70% efficiency, but I doubt that is possible in a home environment. These values of currents include the capacitive charging currents of bushing, bus bars, connectors, very short lengths of cables and the current of voltage instrument transformers.


If represented on a graph, DC can be plotted as a straight line as it does not change direction.
The distance between contacts, the contacts geometry and relative atmospheric condition defines the overvoltage at the instant of strike.
Every strike causes high-frequency currents tending to equalize potentials at the contacts. When the current is interrupted, the voltages at the source side and the loading side will oscillate independently. The source side will follow the power frequency while the loading side will remain at the trapped voltage. As soon as the voltage between contacts exceeds the dielectric strength of the air, at that distance the restrike will occur, and so on.
Successive strikes occurring during the closing and opening operations of the off-loaded bus by the disconnector are shown in Fig.
1 a and b, respectively.When closing takes place, the first strike will occur at the maximum value of the source voltage. As the time passes a series of successive strikes will keep occurring at reduced amplitude, until the contacts touch. When the disconnector opening, restrikes occur because of the very small initial clearance between the contacts.
At the transient beginning, the intervals between particular strikes are on the order of a millisecond, while just before the last strike; the period can reach about one half of cycle at power frequency, Fig. In paper [3] there are up to 5000 restrike registered during switching operation of the disconnector. The maximum value of voltages and maximum value of the wave front increasing will take place at the maximum distance between contacts. For the purpose of the investigation of the insulation strength and induction of electromagnetic interferences (EMI), the most important are the first few strikes during the closing operation or the last few strikes during the opening operation. Each individual strike causes a travelling wave with the basic frequency on the order 0.5 MHz (330 kHz-600 kHz). Very fast transient overvoltage due to the closing operation Channel 1- source side voltage Channel 2-load side voltageThese high-frequency phenomena are coupled with the secondary circuits as a result of various mechanisms.
In large secondary circuits, the potential differences are in the form of longitudinal voltages between the equipment inputs and the equipment enclosures.Depending on the type of secondary circuits used and the way they are laid, differential voltages may also occur. Such a coupling mechanism has a special effect on the secondary circuits of instrument transformers, and particularly on the connected instruments, since these circuits are always galvanically linked to the grounding system.
The difficulty of comparing data comes from the fact that different authors performed measurements at different places (some measurements were made at the closest point to the disconnector being operated whereas others made measurements in the vicinity of the auxiliary equipment, i.e. Little information is available about the grounding practice of the neutral conductor in CT or VT circuits, the quality and grounding of the sable shields as well as how the measurements have been performed. Therefore, the measured levels have to be analyzed very carefully before comparison and drawing any conclusions [5]. Results of up to date measured common mode voltages at secondary circuits of CVT, CT and VT are presented in the paper [5]. There are maximum levels of the common mode voltages ranging from 100 Vpeak up to 2.5 kVpeak in the shields of the secondary circuits cables of the CT and VT. RESULTS OF EXPERIMENTAL MEASUREMENTS ON SITEThe last ten years of extensive analysis of disconnector and circuit breakers generated EMI measurements that have confirmed that disconnector operation with off-loaded busbar is the most important and typical source of interference in secondary circuits of substations.
Measurements of switching overvoltages generated during disconnector operation in the air insulated substation HPP Grabovica on the river Neretva were performed. HPP Grabovica is an important object for operating of electric power system of Bosnia and Herzegovina.
Investigations of operating of air disconnector type Centre-Break were performed in order to determine switching overvoltage levels that can lead to relay tripping in HPP Grabovica [8].During operations of disconnector (synchronization or disconnecting of generator from network) malfunctions of signalling devices and burning of supply units of protection relays were appeared.


Malfunctioning of signalling circuits were lower (not eliminated) with installing shielded cables. Also, independent of switching operation of air insulated disconnectors, during synchronization of generator AG1 on network, it’s happened that one of the pole of 220 kV circuit breaker failures.
Because of that, HPP Grabovica plans to install circuit breakers on generator’s voltage (10,5 kV) [9].The field tests were performed at the test circuit at HPP Grabovica, Fig.
MODELING OF THE TEST CIRCUITComputer simulations were performed on the model of test circuit containing elements drawn in Fig. Overvoltages at busbars were calculated during disconnector closing operations, for the same substation layout on which measurements were carried out.Fig. Water is a covalent molecule held together by shared electrons in the covalent chemical bonds.
Comparison between results of measured and calculated overvoltages certified a good agreement of obtained values.Fig. During electrolysis, the molecule is reduced at the cathode to hydrogen gas and oxidized at the anode to oxygen gas. Waveshape of simulated overvoltage surgeWhen the Capacitive Voltage Divider (CVD) was excluded, there were higher values of calculated overvoltages (15% higher on amplitude and 6 % on frequency). Capacitive divider due to primary resistor equal to 300 W and primary capacitance equal to 1 nF influences on overvoltage at the same measurement point causing attenuation and damping of transient overvoltrages.
In order to reduce EMI in secondary circuits the best way is to reduce sources of interference emission during switching of air insulated disconnector.One of the ways of reducing is to install disconnecting circuit breakers. Substation disconnectors isolate circuit breakers from rest of the system during maintenance and repair.
The maintenance requirements for modern SF6 high voltage circuit breakers are lower than maintenance demands made on disconnectors, which means one of reasons for disconnectors removed. Installing disconnecting circuit breaker there are no needs for switching operation of disconnectors.
With disconnecting circuit breakers it is still possible to isolate the line, but low maintenance requirements means it is no longer necessary to isolate the circuit breaker. With the contradictory information, an experimenter could easily start a fire or get injured in an explosion. The disconnecting breaker had to be designed to safety lock in the open position, and to meet all voltage withstanding capabilities and safety requirements of disconnectors.Another way of reducing sources of interference emission is to install circuit breaker without parallel capacitors to contacts. Voltages are measured in point of connection of VT, CT and PT.TABLE I - MAGNITUDES OF SIMULATED OVERVOLTAGESOvervoltages on generator side of 220 kV CB during switching of disconnectors could be up to 320 V in the case of installing instrument voltage transformer (VT) on generator side of CB without parallel capacitors (near instrument current transformer CT). This case causes installing of circuit breaker at generator’s voltage (10,5 kV) for synchronization of generator to network (better conditions for synchronization). This solution of installing circuit breakers on generator’s voltage resulted from problems have occurred during synchronization of generatror with current 220 kV CB.IV. CONCLUSIONSwitching overvoltages due to disconnector operations have been analysed on the existing 220 kV AIS on HPP Grabovica. The difference between magnitudes of measured and calculated overvoltages is 5 % and 15.6 % on frequency. Seems that there are several of these instructables that claim hydrogen comes off the positive (anode), but its the cathode (negative).
