The AVR controller is a state of the art microcontroller technology based voltage regulating relay product form Proton. The AVR controller has the complete operating logic of the processes preprogrammed.   Operating Modes: The operating mode can be selected using TEST or NORMAL Mode front panel Switch:  NORMAL Mode: > In this mode the AVR is operational. If PT input voltage is less than PT set point voltage minus hysteresis, then HIGH LED glow & there is a pulse of LOWER RELAY as per user setting pulse time & delay between two pulses & it clears if PT input voltage is greater than or equal to PT set point > If PT input voltage is greater than PT set point voltage plus hysteresis, then LOW LED glow & there is a pulse of RAISE RELAY as per user setting pulse time & delay between two pulses, & it clears if PT input voltage is less than or equal to PT set point . > If PT input voltage is less than UV set point then UV relay on & UV LED glow & it clears if PT input voltage is greater than or equal to UV set point plus hysteresis.  TEST Mode: > In TEST mode there is one potentiometer at front side of unit, it is independent of PT supply. As per Potentiometer value voltage , Test Low & Test High LED glows as per PT voltage set point.. Settings: > To enter settings mode press set key and then press increment key for enter the correct password. > The password value can be set by using INC or DEC key & then press ENT key. > Press set key to move to next parameter. To edit parameter press increment/decrement keys > To save and exit SET mode press ENT key. > If no key is pressed then controller automatically goes to initial Display normal mode.> The factory set password is 11.     Latest micro controller based technology.

Protection of 3 Phase devices against Over voltage, Under voltage,Single Phasing, Reverse Phasing & unbalance supply are one of the major issue in electrical systems. For safe running of 3-phase devices, special protections that keep a continuous watch on supply conditions are very essential. The major cause of maximum load burn-out is overloading which occurs due to unbalance supply, Single Phasing & Reverse Phasing conditions. VMR3P detects such Conditions & protect the load from burn out. PROTON's VMR 3P' offer above protections along with 3 digit display showing R-Y,Y-B,BR voltages in scanning mode with precise accuracy. LOWHIGH voltage tripping to ensure trouble free running of 3-phase Loads.

An Earth Fault Relay is a safety device used in electrical installations with high earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected.

Features: • DIN rail mountable • LED indication for relay status • External power supplySignal supply selectable by jumper. • Input voltage can be ACDC of up to 2000V Applications: *Voltage safety monitoring *Overvoltage monitoring *Configuring speed dependent relay by connecting analogue tachogenerator output to the module *Safety voltage monitor in Solar panel

Short-Circuit Currents are currents that introduce large amounts of destructive energy into a power system in the form of heat and magnetic force. A short circuit is also known as a fault. It is a type of current that introduces a significant amount of energy into a power system. It can take the form of either heat or magnetic force. It is a low-resistance energy path that bypasses part of a circuit and causes the bypassed part of the circuit to stop working. The reliability and safety of electric power distribution systems are dependent on an accurate and thorough understanding of the short-circuit fault currents that can exist, as well as the ability of protective devices to interrupt these currents satisfactorily.Short circuit currents pose the most serious general hazard to power distribution system components and are the primary concern in the development and application of protection systems. Short circuit currents, fortunately, are relatively simple to calculate. The basic nature of short circuit currents can be determined by applying three or four fundamental circuit analysis concepts. These ideas will be stated and applied in a step-by-step progression.To correctly apply equipment in accordance with NEC and ANSI standards, short-circuit calculations are required. The amount of detail required to perform these calculations varies greatly depending on the size and utility connection.A Short Circuit study is a thorough examination, analysis, or evaluation of an electrical system to determine the magnitude of currents that can flow during an electrical fault and correlate with those values to the ratings of installations of equipment and short circuit protection devices.It addresses short-circuit analysis activities such as design considerations for new systems, analytical studies for existing systems, and operational and model validation considerations for industrial and commercial power systems. In power systems, a short circuit protection fault study is critical.

The team event is a timing relay, not a peloton of 2, 3 or 4 members. Team members take turns riding, while others rest in the support vehicle and move up the road. Teams have the freedom to decide how often you swap riders, how long each member rides and how much distance each covers. Categories and Timings are based on Team Age and Gender. Team Age is the average racing age of all Team members (total number of years divided by 2,3 or 4 depending on team size). Racing Age is the age each Racer will turn during the calendar year of the race (year of race minus birth year).
