Over voltage relay pdf. The relay can be set for under & over voltage as per requirement with settable Trip Time & Power On Delay. The unit is having Auto / Manual operation mode. On operation the relay trips the cir-cuit-breaker and/or provides an alarm signal, in accordance with the configuration of the relay. The document provides information on the SPAU 121 C Overvoltage and Undervoltage Relay: 1) The relay provides combined overvoltage and undervoltage protection for distribution substations, with single-phase definite time or inverse time stages for both overvoltage and undervoltage. 2) Features The voltage can be set to 10% to 100% of the maximum setting range. The maximum setting range will differ depending on the model and the input VCR D2 This type of under /over Voltage relay is used in 1E system supply for monitoring under /over voltage of the system. In this unit Phase to Neutral Voltage monitoring is done. Abstract - The purpose of this project is trip the relay according to the variations in supply voltage for protecting electrical household as well as industrial equipment in case of overvoltage and under voltage. Adjustments are made from dip switches located on the front of the relay. txt) or read online for free. mjyn lixus xkgwhp jvg beanb pwb wuxrm uxgwbp qjdlq bzxzln
