  2. SAE J3068 - Wikipedia

    en.wikipedia.org/wiki/SAE_J3068

    J3068 defines a system of conductive power transfer to an electric vehicle using a coupler capable of transferring single-phase and three-phase AC power as well as DC power, and defines a digital communication system for control. J3068 also specifies requirements for the vehicle inlet, supply equipment connector, mating housings and contacts.

  3. Root mean square deviation - Wikipedia

    en.wikipedia.org/wiki/Root_mean_square_deviation

    In control theory, the RMSE is used as a quality measure to evaluate the performance of a state observer. [ 10 ] In fluid dynamics , normalized root mean square deviation (NRMSD), coefficient of variation (CV), and percent RMS are used to quantify the uniformity of flow behavior such as velocity profile, temperature distribution, or gas species ...

  4. Mean squared prediction error - Wikipedia

    en.wikipedia.org/wiki/Mean_squared_prediction_error

    It is an inverse measure of the explanatory power of ^, and can be used in the process of cross-validation of an estimated model. Knowledge of g would be required in order to calculate the MSPE exactly; in practice, MSPE is estimated.

  5. Electrical wiring in North America - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring_in_North...

    Several other types of wiring systems are used for building wiring in the United States; these include corrugated metal armored cable, mineral-insulated cable, other types of power cable, and various types of electrical conduit. In industrial applications cables may be laid in cable trays. Cable type TC is especially intended for use in tray ...

  6. Mean squared error - Wikipedia

    en.wikipedia.org/wiki/Mean_squared_error

    The MSE either assesses the quality of a predictor (i.e., a function mapping arbitrary inputs to a sample of values of some random variable), or of an estimator (i.e., a mathematical function mapping a sample of data to an estimate of a parameter of the population from which the data is sampled).

  7. Single-wire earth return - Wikipedia

    en.wikipedia.org/wiki/Single-wire_earth_return

    Conventional 2-wire or 3-wire distribution lines have a higher power transfer capacity, but can require 7 poles per kilometre (12 poles per mile), with spans of 100 to 150 metres (110 to 160 yards). SWER's high line voltage and low current also permits the use of low-cost galvanized steel wire (historically, No. 8 fence wire). [ 9 ]

  8. High-voltage cable - Wikipedia

    en.wikipedia.org/wiki/High-voltage_cable

    High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.

  9. powerCon - Wikipedia

    en.wikipedia.org/wiki/PowerCon

    The type A is blue and used for power sources (power flows out of a blue-ended cable, into a chassis socket). The type B is grey and used for power drains (power flows from a chassis socket into a grey-ended cable). Couplers are available with one chassis socket of each type mounted on the ends of a plastic tube to extend cables. [1] Later [when?
