About This Item
511-1956 is a technical standard for engines rated at 2000 horsepower and below 6600 volts, placing it in the electrical and power engineering context where materials, insulation, fields, and performance must be considered together. It is relevant to equipment where dielectric behavior and electromagnetic effects can influence operation and reliability. As a superseded document, 511-1956 is mainly useful for legacy reference, historical comparison, and understanding earlier design and compliance expectations.
What is 511-1956?
511-1956 defines a standards reference associated with electrically powered engine applications in the 2000 horsepower and below 6600 volts range. Its technical context suggests attention to how engineered materials and dielectric properties support safe and consistent performance under electrical stress. For users working with older specifications, the document can help clarify the requirements or assumptions that shaped equipment design, insulation practice, and related engineering decisions at the time.
Where is 511-1956 used?
This standard is most relevant in settings where medium-voltage rotating or engine-driven equipment is specified, maintained, or reviewed against legacy documentation. It may appear in power generation facilities, industrial drive systems, and engineering archives that still reference older voltage and horsepower classifications. 511-1956 can also be useful during equipment refurbishment, technical audits, and procurement reviews when historical design basis or compliance records need to be checked against earlier practice.
Why is 511-1956 important?
Even though it is superseded, 511-1956 can still matter when teams need a dependable technical reference for older systems. It helps support consistency in design review, documentation control, and maintenance planning for equipment that was built to earlier requirements. Using the correct historical standard can reduce risk during repairs, testing, and replacement-part selection, especially when insulation, dielectric performance, or electrical ratings must align with original specifications.
