What Inspection and Treatment Should Be Done After Transformer Automatic Trip? 1.After the automatic trip of the transformer, the operator should carry out systematic treatment, that is, put in the standby transformer, adjust the operation mode and load distribution, and maintain the operating system and...
Reasons for Transformer Gas Protection Operation 1. There is a slight fault in the transformer, producing weak gas; 2. Air intrudes into the transformer; 3. Lower oil level; 4. The secondary circuit is faulty (for example, the DC system is grounded at...
Abnormal Transformer Sound Causes and Handling Methods Transformer on a power supply, there is a buzzing sound, which is mainly the role of high voltage magnetic flux. In normal operation, the sound of the transformer is uniform. When there is other noise, it should be...
What is the Eddy Current Loss of the Transformer? Eddy current loss is the energy loss caused by induced current in the conductor of transformer when the conductor moves in a non-uniform magnetic field or is in a magnetic field that changes with time. It is...
What are the Measures to Improve the Insulation Condition of Variable Frequency Motor? 1. Select electromagnetic wire with good corona resistance to meet the requirements of high frequency pulse and partial discharge of the motor. General use of polyester imide/polyamide imide composite layer enameled wire,...
What are the General Principles for Transformer Protection Installation? 1. Prevent gas from short circuit inside the transformer iron case and low oil level. 2. The defense transformer coil and lead line phase short circuit, large grounding current power grid side coil lead...
What Should Be Checked for Transformer Differential Protection When Transformer is Put into No-load Operation? Transformer differential protection, in the new installation of the transformer must be under rated voltage to do 5 times of no-load test. The secondary wiring should be checked and...
How to Deal with Transformer Overcurrent Protection Action? 1. If there is no obvious fault, send power. 2. Confirm that it is human error, transformer switch trip caused by protection or contact the main control dispatching to determine the system fault, resulting in the overcurrent...
