Bridge Regulation On Load Tap Change
Factory are used to change either the primary or secondary voltage to more closely match the desired input or output voltage. This is usually done when operating conditions have changed and the voltage is different than what is normally desired or required to re-establish “normal” operating conditions. When this occurs, changing one or more of these taps can more exactly provide the desired voltage. Because it is a change that requires actually moving cables, lugs and conductors, this sort of manual voltage regulation is usually done when all other options have been exhausted and is not usually intended for frequent changes.
Tap changing can control / change the voltage (8 to 10%) at the receiving end by manipulating the reactive power flow. It can also control / change slightly the phase angle (phase shifting) thereby affecting the real power flow. Tap changing can be off-load or on-load. In modern power system practice tap changing is rarely used as it has been found, more often than not, to adversely affect the power system Voltage Stability.
We pride ourselves on quality which is our best selling point. Our business goal is to build smart electrical appliance to match our customer’s requirements. We can satisfy various requirement of tap changer. We can undertake designing and making all kinds of special switches according to the technical parameters, special structure and quality required by the customers.
