What is the second harmonic in relay protection
Second Harmonic (2nd): Predominantly generated during transformer energization, causing inrush currents. These currents can be 6-10 times the rated current, rich in second harmonics (60-70% of fundamental), mimicking fault conditions. What is the role of Harmonic 2 setting in Earth fault protection setting? In case of using phase CT summation for residual current measurement, there is a general agreement that the second harmonic is the preferred harmonic for use in harmonic restraint in current protection relays, especially for. Among these, the second (100/120Hz) and fifth (250/300Hz) harmonics are particularly problematic, necessitating their blockage in protection relays to ensure system reliability. Many modern transformer differential relays employ either harmonic. ABSTRACT —Differential protection using second harmonic suppression is a crucial method for safeguarding converter transformers, particularly against maloperation during energization and internal faults. 8 % of third harmonics) while harmonic component of short-circuit currents is negligible. The relay tripped on inrush current immediately after the collector breaker closed. Figure 1a is the oscillography captured. -
