{"product_id":"metrohm-live-line-indicator-lli","title":"Live Line Indicator Metrohm LLI","description":"\u003cp\u003eHigh Voltage DC Live Line Indicators (LLI) are battery operated electronic units that have been specifically designed to test DC systems, with particular relevance to Mass Transit Railway (Metro) \u0026amp; Tram based models.\u003c\/p\u003e\n\n\u003cp\u003eThree versions of Live Line Indicators are available to cover the most common system voltages of 750V, 1500V, and 3000V DC. Although usually applied to overhead catenaries they can also be used on “third rail” installations. Proving that the system is de-energised, and can thus be safely earthed, is important to both maintenance staff and system security.\u003c\/p\u003e\n\n\u003cp\u003eHigh Voltage DC Live Line Indicators give both visual (high intensity flashing red LED’s) and audible (70 dB) alarm should a conductor under test indicate as live. Each version has a threshold setting of approximately 33% of system voltage, above which the line is deemed to be energised.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eCan be used on DC high voltage overhead lines up to 3000V DC\u003c\/li\u003e\n\t\u003cli\u003eEarth lead and clamp attached to long-length handle\u003c\/li\u003e\n\t\u003cli\u003eRed LED indicators when voltage is detected\u003c\/li\u003e\n\t\u003cli\u003eLoud 70dB alarm when voltage is detected\u003c\/li\u003e\n\t\u003cli\u003eAudible indication: Buzzer, 3.1 kHz tone, modulated @ 2Hz\u003c\/li\u003e\n\t\u003cli\u003eCan also be used on third rail installations\u003c\/li\u003e\n\t\u003cli\u003eBattery check function\u003c\/li\u003e\n\t\u003cli\u003eStandard Thresholds: 250V \/ 500V \/ 1000V DC\u003c\/li\u003e\n\t\u003cli\u003eResistor Chain: 1.5MΩ \/ 3MΩ \/ 6 MΩ\u003c\/li\u003e\n\t\u003cli\u003eOperating time: 5 minutes nominal\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"T\u0026R Test Equipment","offers":[{"title":"Default Title","offer_id":52005514051897,"sku":"HVITRLLI","price":9020.0,"currency_code":"SAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/5669\/1257\/files\/Live_20Line_20Indicators_0317601c-c3b1-424c-957b-cbd750c14a4e.jpg?v=1773300431","url":"https:\/\/www.measure-mart.sa\/ar\/products\/metrohm-live-line-indicator-lli","provider":"Measuremart Global Company","version":"1.0","type":"link"}
