This photo has a caption prepared by the Advertising Department. An oil tank and high-voltage bushing are shown on the left. The sphere gap mounted on top of the bushing is clearly shown. Three 750 kv test transformers are shown in the bay of the "ornate horse barn." This barn was built by O. C. Barber (founder of the town of Barberton, Ohio) sometime around 1910 as part of his several thousand acre estate. A. O. Austin (chief engineer of the Ohio Brass Co. and factory manager of The Ohio Insulator Plant) bought O. C. Barber's mansion and horse barn and approximately 400 surrounding acres in 1926. O. C. Barber had passed away in 1920. The three test transformers were used to charge the wire cage conductor which served as one plate of a large capacitor. This conductor is shown suspended by V strings of insulators attached to wood poles on both sides of the conductor. A conductor mesh buried below ground served as the ground plate of the capacitor. The right (east) and left (west) large sphere gaps were adjustable. The copper spheres were 150 cm (about 60 in.) in diameter and were made by electroplating.
