   Square D is an American manufacturer of electrical equipment headquartered in Andover, Massachusetts. Square D is a flagship brand of Schneider Electric , which acquired the company in 1991. The company was listed on the New York Stock Exchange for 55 years prior to its acquisition without reporting financial loss in any calendar quarter ...

3. Transformer types - Wikipedia

   en.wikipedia.org/wiki/Transformer_types

   A leakage transformer, also called a stray-field transformer, has a significantly higher leakage inductance than other transformers, sometimes increased by a magnetic bypass or shunt in its core between primary and secondary, which is sometimes adjustable with a set screw. This provides a transformer with an inherent current limitation due to ...

5. Voltage transformer - Wikipedia

   en.wikipedia.org/wiki/Voltage_transformer

   A 120:120 instrument isolation transformer showing two polarity marking conventions. Voltage transformers (VT), also called potential transformers (PT), are a parallel-connected type of instrument transformer. They are designed to present a negligible load to the supply being measured and have an accurate voltage ratio and phase relationship to ...

7. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   Transformers designed for below-grade installation can be designed for periodic submersion in water. [14] Distribution transformers may include an off-load tap changer, which slightly adjusts the ratio between primary and secondary voltage to bring the customer's voltage within the desired range on long or heavily loaded lines. [citation needed]

8. Copper loss - Wikipedia

   en.wikipedia.org/wiki/Copper_loss

   For low-frequency applications, the power loss can be minimized by employing conductors with a large cross-sectional area, made from low-resistivity metals.With high-frequency currents, the proximity effect and skin effect cause the current to be unevenly distributed across the conductor, increasing its effective resistance, and making loss calculations more difficult.

9. Tap changer - Wikipedia

   en.wikipedia.org/wiki/Tap_changer

   However, a transformer may include a tap changer on each winding if there are advantages to do so. For example, in power distribution networks, a large step-down transformer may have an off-load tap changer on the primary winding and an on load automatic tap changer on the secondary winding or windings. The high voltage tap is set to match long ...
