Over Current Relay monitors general balanced overloading and has current\/time settings. These settings determine the protective schemes. The relay is IDMT type which has different tripping time characteristics with different current conditions. These are classified in accordance with their characteristic curves which indicate the speed of tripping operation. The typical settings for relay is 0.5-2 Amp in 1-10 seconds.<\/p>\n<p>Nvis 7091 has accurate voltage, current &amp; time measurement.It includes built-in variable supply, digital voltmeter, ammeter, timer. The timer operation is automatic when current is applied to relay. This automatic operation ensures accurate tripping time measurement.<\/p>\n<p>Nvis 7091, Over Current Relay Testing System is an ideal platform to enhance education, training, skills &amp; development amongs our young minds.<\/p>\n<p>Product Features<\/p>\n<ul>\n<li>\u00a0Alphanumeric 16X2 Big Font LCD for better visibility<\/li>\n<li>\u00a0Electromechanical relay to understand internal mechanism and its working<\/li>\n<li>\u00a0Simultaneous display of voltage, current on LCD<\/li>\n<li>\u00a0Inbuilt automatic timer that starts and stop with relay<\/li>\n<li>\u00a0Inbuilt Power Source for relay<\/li>\n<li>\u00a0Diagrammatic representation of relay connection in transmission line<\/li>\n<li>\u00a0Exclusive and attractive design<\/li>\n<li>\u00a0Designed by considering all the safety standards<\/li>\n<li>\u00a0Learning material CD<\/li>\n<\/ul>\n<h6>Scope of Learning<\/h6>\n<div class=\"tech_specs\">\n<ul>\n<li>To study the IDMT Over Current Relay &amp; its applications<\/li>\n<li>To study and use plug setting multiplier<\/li>\n<li>To study and use time setting multiplier<\/li>\n<li>To study and verify the operating Characteristics of Over Current Relay at various plug &amp; time settings<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Nvis 7091 Over Current Relay Testing System is a useful learning product for electrical laboratories.
