Over Voltage Under Voltage Protection Relay

Under voltage wave form.

Over voltage under voltage protection relay.

The following protection functions are used in this relay. This is because of the high potential. Apart from its well established product range selec is also rapidly growing in the area of digital panel meters plcs. Geya under over voltage relay provides protection to equipment that cannot handle excess voltages.

I ve presented this way it is over under voltage protection circuit. Reason under voltage protection. The components required for the block diagram of the comparator circuit is the power supply step down transformer bridge rectifier two preset pins comparators voltage regulator relay buzzer and ac current this circuit is planned to expand a low voltage and high voltage tripping mechanism to protect the load from the damage. Over and under voltage protection of electrical appliances this is an over and under voltage protection to all electrical appliances are safe.

Similarly for under voltage protection lower comparator energizes the relay when the supply voltage falls below 180 v by maintaining 6v at the inverting terminal. I e the output from the generator s lavt potential transformer will be given to the under voltage coil typically 110 volts relay coil. Which cut off currents with power relay. We use electronics circuits high accurate work is fast lm393 an6780 and more.

Is an indian manufacturer of electrical measurement electrical protection time relays process control and automation components. Over voltage and under voltage circuit using comparator. Sold by partgry t and ships from amazon fulfillment. Under voltage protection 27 over voltage protection 59 voltage transformer supervision 60vts 1.

The under voltage and the overvoltage protection circuit is a circuit which protects you from the higher voltages and the lower voltages conditions. Under voltages occur due to several reasons like any faults on the system. As long as the monitored voltage remains below the maximum voltage the equipment can withstand the relay remains de energized and remains closed keeping the load energized. Increase in the amount of loading loss of an incoming transformer etc.

For the lower voltage you can see some flickers in the lights and for the higher voltage one the circuit will be fully damaged. Our under over voltage relay have indications the green indicator. Since its foundation in 2000 selec has become the market leader for timers counters and temperature controllers in india.
