VTOC-350
Fabrication
The capacitor stacks are made up of individual capacitor elements wound using a mix of kraft paper and polypropylene film series. The capacitor elements are connected utilizing low inductance copper tabs. The elements are mechanically compressed and bound into a stable assembly which provides consistent accuracy performance over the life of the transformer. Each assembly is installed into a hollow core porcelain insulator, vacuum processed and filled with a synthetic capacitor fluid. The capacitor stack is hermetically sealed utilizing a stainless-steel bellows allowing for expansion of the fluid within a wide range of temperatures.
The electromagnetic unit (EMU) is housed in a cast aluminum tank at the base of the transformer and steps down the intermediate voltage of the capacitor stack to voltages suitable for relaying and metering applications.
All VTOC’s are equipped with a passive ferro- resonance suppression circuit, external grounding switch, 5kV HO bushing, level indicator, 3⁄4” drain plug and ground pad.
Accuracy
Designed to provide 0.3% accuracy class when loaded with IEEE burdens of W, X, Y, Z and up to ZZ. Optional High Accuracy 0.15% class is available at W, X, Y and Z Burdens.
Testing
Every transformer is tested in accordance with IEEE Standard C57.13.9 (latest revision). Standard tests include applied and induced voltage, polarity, dissipation factor and capacitance, ferro-resonance test, accuracy, ratio, and partial discharge. All units are guaranteed to be PCB free.
