It provides advanced protection functions including multi-zone differential protection, restricted ground fault, overcurrent, voltage, and frequency elements to ensure reliable power grid operation.\u003c\/p\u003e\n\u003ch3\u003eProtection Features and Differential Restraint\u003c\/h3\u003e\n\u003cp\u003eThe relay features a dual-zone percentage differential protection scheme with pre-set differential restraint characteristics. The minimum pickup range is adjustable from 0.05 to 1.00 pu, while Slope 1 and Slope 2 ranges span 15 to 100% and 50 to 100% respectively. Kneepoint 1 is configurable from 1.0 to 4.0 pu, and Kneepoint 2 ranges from 4.0 to 30.0 pu to handle high external fault currents and CT saturation.\u003c\/p\u003e\n\u003ch3\u003eHarmonic Inhibit and Operate Times\u003c\/h3\u003e\n\u003cp\u003eTo prevent maloperation during transformer energization and overexcitation, the unit incorporates configurable 2nd and 5th harmonic inhibit ranges from 1.0 to 40.0%. Operate times vary based on harmonic blocking selection, ranging between 20 to 30 ms when harmonic inhibits are selected, and dropping to 5 to 20 ms when no harmonic inhibits are selected. Level accuracy is maintained at within ±0.5% of reading or ±1% of rated value, with a dropout level of 97 to 98% of pickup.\u003c\/p\u003e\n\u003ch3\u003eTechnical Parameters\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eT60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrdering Code \/ MPN\u003c\/td\u003e\n\u003ctd\u003eT6M-9HH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eTransformer Protection Relay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Application\u003c\/td\u003e\n\u003ctd\u003ePower transformer protection and monitoring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Pickup\u003c\/td\u003e\n\u003ctd\u003e0.05 to 1.00 pu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlope 1 Range\u003c\/td\u003e\n\u003ctd\u003e15 to 100%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlope 2 Range\u003c\/td\u003e\n\u003ctd\u003e50 to 100%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKneepoint 1\u003c\/td\u003e\n\u003ctd\u003e1.0 to 4.0 pu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKneepoint 2\u003c\/td\u003e\n\u003ctd\u003e4.0 to 30.0 pu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2nd Harmonic Inhibit Range\u003c\/td\u003e\n\u003ctd\u003e1.0 to 40.0%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5th Harmonic Inhibit Range\u003c\/td\u003e\n\u003ctd\u003e1.0 to 40.0%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperate Time (Harmonic Inhibits Selected)\u003c\/td\u003e\n\u003ctd\u003e20 to 30 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperate Time (No Harmonic Inhibits Selected)\u003c\/td\u003e\n\u003ctd\u003e5 to 20 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDropout Level\u003c\/td\u003e\n\u003ctd\u003e97 to 98% of pickup\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLevel Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.5% of reading or ±1% of rated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfiguration Software\u003c\/td\u003e\n\u003ctd\u003eGE EnerVista UR Setup\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the primary function of the GE T60 T6M-9HH relay?
