Frequently Asked Questions about T60-G11-HKH-F8L-H6N-M8L-P6M-UXX-WXX
What is the purpose of a T60-G11-HKH-F8L-H6N-M8L-P6M-UXX-WXX GE Multilin universal relay?
The T60-G11-HKH-F8L-H6N-M8L-P6M-UXX-WXX is designed as a full-featured, multiple-winding transformer protection universal relay. In other words, it is able to provide protection for medium to large power transformers. The T60 can compensate for transformers that may have a range of grounding configurations with a T60 algorithm. This algorithm allows the user to remove the zero-sequence current to achieve this goal. An integral benefit of the T60 Multilin is the ability to provide the transformers with protection from ground faults down to 5% in order to minimize damage. Similarly, the T60 is able to monitor thermal conditions and provide optimal security with an adaptive second harmonic restraint algorithm.
What are the overcurrent functions of the GE Multilin T60-G11-HKH-F8L-H6N-M8L-P6M-UXX-WXX?
The T60-G11-HKH-F8L-H6N-M8L-P6M-UXX-WXX has overcurrent functions which allow the unit to provide overcurrent elements of thermal overload, instantaneous, and time in the varying directionals of phase, neutral, neutral direction or ground. The neutral directional element is able to differentiate between voltage or current polarization. Each element can run simultaneously with a primary differential protection or can run individually to provide primary protection when the other protection elements have been blocked.
What is the inrush inhibit function of the T60-G11-HKH-F8L-H6N-M8L-P6M-UXX-WXX?
The inrush inhibit function is able to cover the energization characteristics of transformers by being set to either adaptive or traditional mode. This secures protection during inrush situations even if the second harmonics are weak.
