Product descriptions from the supplier
Overview
This series of tapping switches are applied to the oil immersed transformer with frequency 50HZ、60Hz, rated voltage 10KV～35KV,rated current 63A～250A, Before changing the voltage, must cut of the power of the transformer, changed the turns of coil under off-circuit condition so as to realize the purpose of adjusting the voltage of the transformer; finally reach the purpose to adjust the secondary output voltage.
Changing the tapping position by such way: rotate the handle to drive the shaft, then the shaft drive the moving contactors. Thereby changing the transformer primary windingturns in order to change the transformer voltage and adjust the secondary voltage.

Why Can't VT Be Shorted & CT Be Opened? ExplainedWe all know that a voltage transformer (VT) must never operate short-circuited, while a current transformer (CT) must never operate open-circuited. Short-circuiting a VT or opening the circuit of a CT will damage the transformer or create hazardous conditions.From a theoretical standpoint, both VTs and CTs are transformers; the difference lies in the parameters they are designed to measure. So why, despite being fundamentally the same type of device, is one prohibited from short-circuit operatioEcho10/22/2025 -
Why Are Voltage Transformers Burning Out? Find the Real CausesIn power circuits, voltage transformers (VTs) are often damaged or burned out. If the root cause is not identified and only the transformer is replaced, the new unit may quickly fail again, disrupting power supply to users. Therefore, the following checks should be performed to determine the cause of VT failure: If the voltage transformer has ruptured and oil residue is found on the silicon steel laminations, the damage was likely caused by ferroresonance. This occurs when unbalanced voltages orFelix Spark10/22/2025 -
Things to Know When Operating Voltage Transformers: De-energizing and Energizing ProceduresQ:What are the Operating Sequence Rules for the Secondary Miniature Circuit Breaker and High-Voltage Power Supply During Voltage Transformer De-energizing and Energizing?A:For busbar voltage transformers, the principle for operating the secondary miniature circuit breaker during de-energizing and energizing is as follows: De-energizing:First, open the secondary miniature circuit breaker, then disconnect the high-voltage power supply of the voltage transformer (VT).

How to Safely Operate & Maintain Current Transformers?I. Permissible Operating Conditions for Current Transformers Rated Output Capacity: Current transformers (CTs) must operate within the rated output capacity specified on their nameplate. Operation beyond this rating reduces accuracy, increases measurement errors, and causes inaccurate meter readings, similar to voltage transformers. Primary Side Current: The primary current may continuously operate up to 1.1 times the rated current. Prolonged overload operation increases measurement errors and mFelix Spark10/22/2025 -
How to Operate & Maintain Voltage Transformers Safely?I. Normal Operation of Voltage Transformers A voltage transformer (VT) may operate long-term at its rated capacity, but under no circumstances should it exceed its maximum capacity. The secondary winding of a VT supplies high-impedance instruments, resulting in a very small secondary current, nearly equal to the magnetizing current. The voltage drops across the leakage impedances of both primary and secondary windings are therefore very small, meaning the VT operates close to no-load under normaEdwiin10/22/2025 -
How to Improve Rectifier Transformer Efficiency?
