What is a digital timer relay used for?

Digital time relay is used for relay protection. It can shorten the level difference of the overcurrent protection, reduce the maintenance amount, and improve the correct action rate of the protection. It protects the safe and stable operation of the main system and main equipment. Because the timer relay has the characteristics of high precision, good stability, convenient and intuitive setting, no need for calibration to change the setting value, and wide setting range. Therefore, digital time relays are widely used in power systems.
