Zero sequence transformer effect: when an electric shock or leakage circuit when a fault occurs, the protection action, cut off the power supply. Use: can be mounted on a three-phase line each current transformer, or let the three phase conductors together through a zero-sequence current transformer can also be installed in a zero-sequence current transformer on the neutral line N, use it to detect three-phase current vector. Zero sequence current transformer is made of ABS plastic shell, the whole cast resin into a sealed, effectively avoiding rust transformer in the process of long-term use. Suizhou high voltage transformer insulation performance Which is good, beautiful appearance. High sensitivity, good linearity, reliable operation, easy installation and so on. Its performance is better than the average zero-sequence current transformer, using a wide range, not only for high-voltage transformer electromagnetic relay Jiaozuo Which is good, but also applies to electronic and computer protection. DC transformer error measuring method: compare the difference between the number of turns of compensation only play the role of compensation, the compensation amount has nothing to do with the secondary load and current size. Compensation is generally only a few turns of the high-pressure transformer turns Xinxiang Which, turns the current low end of the compensation should be calculated maximum secondary resistance, and current high-end secondary impedance minimum error. For high-precision micro-current transformer turns compensation compensation even if only one turn, would compensate for the excess. Then you can turn or fractional turns semi compensation. But the number of turns of the current transformer is based on a closed loop through the core window is computed, the number of turns of the current transformer is one turn one turn calculated half turn of absence. Semi-turns or fractional compensation must turn aids such as: double winding, two-core and so on.
