  • Vacuum Circuit Breaker

    Vacuum Circuit Breaker

    Request for Price

    iCB series comprises embedded pole type vacuum circuit breakers for medium voltage and indoor use. They are suitable for three phase AC operations for 12kV, 17.5kV, 24kV and 36kV and are used for the protection of the electrical equipment in various industries, mining, and especially for medium voltage distribution sub stations, together with suitable air-insulated cubicles.The iCB used German Technology and is available in complete series for medium voltage and for all commonly used rated currents, from 630A to 4000A, and for rated breaking current up to 40kA. The iCB circuit breaker come with a mechanical lifetime of 30,000 operations. The embedding with epoxy resin covers the vacuum interrupter as well as the upper and lower contacts of the circuit breaker, thus creating a full insulation for the internal electrical circuits. The embedding is done with a fully automated process, the APG (automated pressure gelatin) process. Thus, the iCB is no longer subjected to environmental hazards, and is fully maintenance free in this aspect. A special flexible bedding fills the space between the vacuum interrupter and the epoxy resin, creating a cushion that responds to all thermal expansions and contractions, safeguarding the iCB from the occurrence of any electrical gap and therefore flash overs. The embedded pole technology protects the circuit breaker from shock and mechanical stress, pollution and condensation. Flash overs between the interrupters are now virtually a thing of the past. Also, the creep age length of the interrupter and therefore the voltage withstand level (BIL) of the circuit breaker increase dramatically, opening new dimensions in cubicle design. The use of modern, small-size vacuum interrupters with first class technology, the above features ensure the highest level of reliability for the iCB circuit breaker. While meeting all relevant standards, with a lifetime of over 30,000 mechanical operations, and the ability to function as a recloser, the iCB can surely meet the highest demands of the industry. Last not least, the high level of automation and technology used make the iCB also economically competitive and interesting for panel builders around the world.   Application Suitable for 3-phase AC operations for 12kV, 17.5kV, 24kV and 36kV Medium voltage distribution sub stations

This data is collected in the form of measured analog current or voltage values or the open or closed status of contact points. Acquired data can be used locally within the device collecting it, sent to another device in a substation, or sent from the substation to one or several databases for use by operators, engineers, planners, and administration.   SupervisionComputer processes and personnel supervise, or monitor, the conditions and status of the power system using this acquired data. Operators and engineers monitor the information remotely on computer displays and graphical wall displays or locally, at the device, on front-panel displays and laptop computers.ControlControl refers to sending command messages to a device to operate the I&C and power-system devices. Traditional supervisory control and data acquisition (SCADA) systems rely on operators to supervise the system and initiate commands from an operator console on the master computer. Field personnel can also control devices using front-panel push buttons or a laptop computer In addition, another task is power-system integration, which is the act of communicating data to, from, or among IEDs in the I&C system and remote users. Substation integration refers to combining data from the IED’s local to a substation so that there is a single point of contact in the substation for all of the I&C data. Power-system automation processes rely on data acquisition; power-system supervision and power-system control all working together in a coordinated automatic fashion. The commands are generated automatically and then transmitted in the same fashion as operator initiated commands.

  • Over Voltage Relay

    Over Voltage Relay

    Request for Price

    MVT 181 is a numerical true RMS single pole relay consists of two elements. Each element can be selected for under voltage function or over voltage function or switched off. The characteristics setting, voltage setting and time multiplier setting are independently settable for each element and the voltage setting is in terms of voltage. Hence this relay can be used as a two stage under voltage or two stage over voltage protection. Multiple Characteristics:There are four operating characteristics for over voltage function and two operating characteristics for under voltage function. Overvoltage Characteristics:Definite Time Lag (DTL) Long Time Inverse (LTI) Extremely Inverse 1(El 1) Extremely Inverse 2(El 2) Undervoltage Characteristics:Definite Time Lag (DTL) Extremely Inverse 1(El 1) Two elements:Two stage O/V Two stage U/V Or one O/V and one U/V Timer:The relay is provided with two status inputs, one of which is to be connected across the circuit breaker auxiliary contact 52a. From this the circuit breaker closed or opened condition is found out. This information is used to introduce a time delay between successive switching of the capacitor banks which allows the capacitor bank to discharge to a safer value after disconnected from a live network. This timer function is a settable one and its output (N/O) contact is used in the closing circuit of the circuit breaker. The completion of this time delay is also indicated by ^TIMER^ LED in the front fascia. In addition the same status input can be used for Trip circuit supervision also. During other under voltage and over voltage applications this timer function can be disabled or used as an independent timer function. Trip Circuit Supervision:Pre-closing and post-closing supervision of the trip circuit and trip supply is possible with this relay. A low value of DC current is passed through the entire trip circuit to monitor the trip coil, its auxiliary switch and the associated wiring. One of the status input is connected across the tripping contact and another status input is connected across the 52a contact (auxiliary contact of the circuit breaker) in series with the trip coil. During trip circuit fail condition the monitoring current flow ceases and the energised status input drops off and the relay gives a contact output to indicate this condition. In addition to this contact an LED is provided in the front fascia to indicate the ^T.C. FAIL^ condition. A time delay of approximately 400 msecs has been given to avoid false trip circuit fail indication at the time of normal tripping. Thus trip circuit supervision is the integral part of the relay. If this function is not required the same can be put off in the setting menu.

The dip switches on the relay front fascia select different operating functions and time setting.there is a watchdog timer in the relay which continuously monitors the program, put off ^power on^ led indication if the watch dog timer elapses.to start an auto re close cycle, the initiating contact from the protective relay must be closed without chatter for at least 12 milliseconds.inputs:two optically isolated inputs are provided. One is used to take the three phase protection operated contact inputs to initiate the auto rec lose relay.the another input is used to block the re close functions if the external blocking input is initiated.reclose timer:the relay has four re-close timers. The relay selects the respective timer sequentially depending upon the number of re-close selection and the re-close initiation.reclaim timer:there is the common reclaim timer. It operates in series with the re-close timers. The over all reclaim time delay from the relay initiation to relay reset is therefore reclaim timer setting plus re-close time. For every initiation the reclaim time counting are resets automatically.lockout function:when the number of shots switch is in off mode the protection operated contact input initiation condition it will energize the lockout relay and lockout led indication and it blocks the re-close function.when the external blocking input is initiated, the re-close function is blocked and it energize external blocking led, lockout led and lockout relay.as the relay allows the maximum of four re-close depending upon the number of shots selection, the number of shots is less than the number of initiation within the reclaim time it will energize the lockout relay and its led indication.
