This autocut circuit is very easy simple and very useful.

Over voltage protection relay circuit. In the normal operating conditions between 160 and 250 v the output of the timer 1 is held low so the transistor 1 is in cutoff state as a result the reset pin of the timer 2 is high which causes to output at pin 3 is high so the transistor 2 conducts and then the relay coil gets energized. Generally zener diode based electronic circuit are mostly used for small level overlarge protection. Only one transistor and some other components are used in this overvoltage protection auto circuit. Circuit of over voltage and under voltage protection using a comparator the ic rex bit is an input pin of ic1 is computing to the 12v power supply is fixed to the ic2.

This is a safety device to overvoltage. This is a shunt regulator diode. Over voltage protection circuit using tl431 shunt regulator ic. The pcb for our mains overvoltage protection circuit is designed for a single sideboard.

Thus we can consider as an ic op amp and its pressure act as an ic2 1 is a high voltage detector high voltage ics current works to the transistor q1 and the relay function. In electrical engineering a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. An overvoltage protection circuit will operate when the supply voltage increases up to 110 to 130 above the rated voltage of a device. The over voltage protection circuit may be constructed using discrete components integrated circuits mechanical devices such as relays etc.

The 2d image of my board design is shown below. Automatic equipment disconnect when the power cross the level of a fixed voltage. Generally fuse or mcb is used for overvoltage protection however in this project our aim is to make a circuit which can perform better than a fuse or mcb and overcome the. This circuit is a very useful auto cut circuit to the protection of any electrical or electronics appliance from high.

Short circuit protection reverse polarity protection and over under voltage protection are some of the protection circuits that are used to protect any electronic appliance or circuit from any sudden mishappenings. These can either connected internally or externally depending on the circuits involved. This circuit protects from high voltage. This way it will cut off the power supply to protect the device from overvoltage which may cause to damage.

4 the first protective relays were electromagnetic devices relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over current over voltage reverse power flow over frequency and under frequency. Overvoltage protection circuit using timers. For the lower voltage you can see some flickers in the lights and for the higher voltage one the circuit will be fully damaged. This is because of the high potential.

Mains over voltage protection circuit pcb design. Load is connected with nc normally connected pin of the relay.
