  • Page 93 SANTERNO USER MANUAL ● High power loss: High-voltage power loss is usually caused by normal switch operation. If the unusual high-pressure breaking (without trouble record, no break operation) occurs, check the switchgear breaker circuit. ● VFD over current: When VFD output current is 1.5 times larger than rated current, then over current will protect.
  • Page 94 ● Fuse fault: The fuse fault will be alarmed when a phase loss is detected. Check whether caused by main circuit power loss, or whether the three-phase input terminal is loosen; whether the input fuse is intact. If the fuse is open, please replace the cell. ●...

    The power cells within the cell cabinet have exactly the same electrical and mechanical properties. If a failure caused by malfunction of power cell is identified, it can be cleared by replacing. the fault power cell with a new one. After replacement, please contact with Santerno, to maintenance the fault power cell.

    Temperature Controller of Dry-type Transformer Setting Instruction Caution! Before the testing of the withstand voltage, the sensor cable plug should be separated from the temperature control instrument first, so as to avoid damage to the temperature control instrument ! A.1 Overview of LD-B10 series instruments A.1.1 Features LD-B10-10 series temperature controller of dry transformer(referred to as temperature controller) is an intelligent controller designed specially for safe operation of dry transformer.
