Voltage Sensor Machining for Electrical Power Transformers


This part is a tap adapter bushing, more commonly called a voltage sensor. It is used in power transformers to monitor the flow of energy in the coils. If the flow is too low, it signals the engineers that the power distribution grid needs maintenance! Many materials go into the making of a voltage sensor, including copper and tin for the internal components, and an external body made of aluminum and zinc to protect the inner circuitry from corrosion.
