Several solutions to prevent the secondary side of the CT from opening
Several solutions to prevent the secondary side of the CT from opening:
1. Check the secondary circuit of the current transformer regularly to ensure that the connection is firm and not loose.
2. For the current transformer that has not been used for a long time, check it first and confirm that it works normally before use.
3. When installing the current transformer, attention should be paid to the insulation of the secondary side line to avoid leakage and short circuit.
4. When using the current transformer, avoid the secondary side interface being wet or soaked by rain to avoid short circuit and leakage.
In a word, the CT is an indispensable and important equipment in the power system, but the second side opening may lead to serious safety problems. Therefore, we must treat the secondary side open circuit of the CT seriously, and take corresponding measures to ensure the normal operation of the power system.
In addition to the solutions mentioned above, there are some other preventive measures that can be taken. For example, a current switch can be installed on the secondary side of a current transformer to automatically cut power if an open secondary side is detected, thereby preventing damage to the system. In addition, a dual secondary side design can be used, where the secondary side of the CT is divided into two separate lines, so that if one line is open, the current signal can still be supplied through the other line.
In a word, CT is an essential equipment in power system, but second side opening may lead to serious safety problems. Therefore, we must take appropriate measures to avoid secondary side open circuit to ensure the normal operation of the power system
