Dec 30,  · Voltage Transformer or Potential Transformer Theory. The secondary voltage of the PT is generally V. In an ideal potential transformer or voltage transformer, when rated burden gets connected across the secondary; the ratio of primary and secondary voltages of transformer is equal to the turns ratio and furthermore. VOLTAGE TRANSFORMERS. Two types of voltage transformer are used for protective-relaying purposes, as follows: (1) the "instrument potential transformer," hereafter to be called simply "potential transformer," and (2) the "capacitance potential device.". A potential transformer is a conventional transformer having primary and secondary windings. For example, the insulation class of a potential transformer used on a / volt system should be 15 KV even though the PT has a primary rating of volts and is connected phase-to-ground. Similarly, any current transformer used on a /Y volt system should be of the 15 KV insulation .

These potential transformers will be used as Bus-Bar P.T. for voltage The potential transformers shall be electromagnetic, outdoor type, single phase, oil filled. For example, the insulation class of a potential transformer used on a / volt system should be 15 KV even though the PT has a primary rating of volts and is connected phase-to-ground. Similarly, any current transformer used on a /Y volt system should be of the 15 KV insulation . WBSETCL / TECH SPEC / Rev Page 2 of 9 Potential Transformer TECHNICAL SPECIFICATION FOR POTENTIAL TRANSFORMERS 1. SCOPE: i) This specification covers the design, manufacture, assembly, testing at the manufacturer's works, supply, delivery at site of potential transformers in three phase system of KV, KV and 33 KV class. Transformers: Basics, Maintenance, and Diagnostics. due to voltages induced in the steel of the core, which is constantly subject to alternating magnetic fields. Steel itself is a conductor, and changing lines of magnetic flux also induce a voltage and current in this conductor. Split-Core Current Transformers. This type of current transformer is available to measure AC currents from A to A, at 50 to HZ. They are very popular in sub-metering applications where existing systems are being upgraded and it is impractical to isolate the primary conductor. Laminated core. This is the most common type of transformer, widely used in electric power transmission and appliances to convert mains voltage to low voltage to power electronic devices. They are available in power ratings ranging from mW to MW. The insulated laminations minimizes eddy current losses in the iron core. Dec 30,  · Voltage Transformer or Potential Transformer Theory. The secondary voltage of the PT is generally V. In an ideal potential transformer or voltage transformer, when rated burden gets connected across the secondary; the ratio of primary and secondary voltages of transformer is equal to the turns ratio and furthermore. Types of Transformers. The transformers are classified based on voltage levels, Core medium used, winding arrangements, use and installation place, etc. Here we discuss different types of transformers are the step up and step down Transformer, Distribution Transformer, Potential Transformer, Power Transformer, 1-ϕ and 3-ϕ transformer, Auto transformer, etc. Potential Transformer (PT) Types of Potential Transformer. Ratio and Phase Angle Errors of Potential Transformer. Burden of a Potential Transformer. Phasor Diagram of a Potential Transformer. Applications of Potential Transformer. VOLTAGE TRANSFORMERS. Two types of voltage transformer are used for protective-relaying purposes, as follows: (1) the "instrument potential transformer," hereafter to be called simply "potential transformer," and (2) the "capacitance potential device.".
