Panel TVSS   Overview of Transient Voltage Surge Suppressors                     Few Questions ?   If UPS is there Why TVSS is required ? Is this a form of substitute to other Power Conditioning Devices?     First Level Understanding on Concept.   A very basic Power Solution available for Power problems   For IT and Telecom related Loads.   For Industrial Loads I.e CNC controllers, steel mills etc.   For loads which are at remote site where quality of Power is not good.  POWER QUALITY DEFINITIONS PER IEC/IEEE     Transient                 Short duration Voltage , Current or Power problem  lasting typically  Surge                      Voltage increase of typically > 2 X  the peak nominal system.   Line Noise                High frequency voltage or current typically     T.O.V.                     Temporary increase in RMS voltage    1.1 - 1.4pu Temporary               Duration  26/31Cycles - 1 min. Overvoltage  Swell                     Instantaneous increase in RMS voltage nominal  1.1 - 1.8pu Duration  .5 - 25/30 cycles    Sag                       Instantaneous drecreese in RMS voltage nominal  .1 - 0.9 Duration .5 - 25/30 cycles   Overvoltage            Increase in RMS voltage  1.1 - 1.2 pu Duration >1 min. Undervoltage          Decreese in RMS voltage  0.8 - 09pu Duration > 1 min.                                                   Origin of Surge   Surge Voltage Occurs During Switching operations in electrical Systems Conductor loop formation from conductors from the main supply and data transmission Eratic power supply from the source / sub station. Lighting discharges (direct and indirect )in the vicinity of installations.     How Surge voltage travel   The coupling of surge voltage from one systems to another can be inductive, capacitive or galvanic. Inductive Coupling Capacitive Coupling Galvanic Coupling Inductive Coupling This occurs with magnetic field of a current carrying conductor. This magnetic field induces the voltage peaks in near by current loop. Capacitive Coupling Possible discharge from one conductor to another conductor where there are large potential difference Galvanic coupling Here surge voltages couple directly from the interference source to susceptible equipment using common impedences.   How surge Travells ……..   The chances of surge entering in to the system are from three lines   1. Power 2. Signalling 3. Communication and data Line.     Transient Voltage surges : Effects     Surges destroy or damage computer and electronic systems Other effects of transient voltage surges: Disruption and inconvenience caused by system downtimes Financial cost of loss of production Corruption of files and loss of data Repair/replacement cost of damaged equipments   Effective Protection Circle   A Comprehensive Surge protection installation system requires the protections from all the three sides.     What is TVSS ?   lTransient Voltage Surge Suppressor as the name suggest is the protection device which protects any critical load from the Surges , spikes generated through the various power sources.     How TVSS Works     Transient voltage surge suppressors operate instantaneously to divert a surge current to ground    Safe guard all types of electrical & electronic devices from high voltage transients caused due to lighting and large-magnitude surges. Protecting devices are known by names such as:   Lighting arrestors Surge arrestors Lighting protection devices .etc. Types Of TVSS   The types of surge suppressing devices are:   Line Cord Hard- Wired Wall Plug Power Control Centers

Scanning and Data Solutions specialize in the conversion of hard copy information into digital formats.   There are many advantages to Scanning your information and as the speed and efficiency of scanning has improved so dramatically in recent years, the cost implication is far less of an issue. Below are a few advantages to scanning, whatever the format is that you wish to scan (documents, drawings, etc).   Space Saving -  As space in offices is becoming more and more expensive and valuable, many companies will calculate the actual cost of storage as well as the potential earning power if the space was available.       Data Backup -  Disaster recovery, cost justification of losing critical information, whether the threat is fire, water, loss, or general degradation.       Degradation of Quality -  Information is constantly degrading, through constant use and general ageing.  Documents, drawings and micro-formats become torn, faded and possibly brittle.  Scanning the information will capture the image and the scan will not degrade.       Accessibility, Time Saving -  Make information available to people at there desks.  Remove the need to have staff wandering around looking for documents.  Scanned information can be made available over your network so that the information can be searched, viewed and printed in a fraction of the time.       The best thing is you wont have to re-file anything! Which also removes the possibility of miss-filing a piece of information.       Distribution -  Information can be easily distributed, not just internally but externally via email etc, saving time, effort and postage costs.   Recovering Lost Information -  During the scanning process you will be amazed at the number of documents, drawings that you thought were lost that reappear from a simple miss-filing error.
