N396 wattmeter self-recording shield (N 396, N-396, h 396, h 396, h -396)
P rednaznachen for: measurement and continuous recording of the value of active power in networks of single-phase AC 50Hz. According to the manual is designed for use in dry heated rooms at an ambient temperature of 10 ° to 35 ° C and 80% relative humidity at 25 ° C .
N396 wattmeter self-recording shield (hereinafter - devices) are for: measurement and continuous recording of the value of active power in networks of single-phase AC, 50 Hz.
Operating conditions Wattmeter N396 recording shield designed for use in dry heated rooms at an ambient temperature of 10 ° to 35 ° C and 80% relative humidity at 25 ° C.
N396 recording wattmeter panel, for export to countries with tropical climates, is designed to operate at an ambient temperature of 5 to 50 ° C and relative humidity 95% at 40 ° C in closed rooms without sharp changes in temperature, solar radiation, Rain, dust. Possible effect of mold and other biological factors.
In this case, the plant designation device must be complemented by a "0 4.2 **"
Technical data
Maximum permissible error of the instrument to measure and record the measured value is equal to ± 1,5% of full scale range. Maximum permissible error on the recording time is ± 0, 5%.
Limit of allowable total error Wattmeter N396 device on record the measured value is equal to ± 1,5% of full scale range.
The limit of additional error device to measure and record the measured value, due to changes in ambient temperature from normal to any temperature between 10 and 35 ° C, equal to the limit of permissible basic error for every 10 ° C change.
The limit of additional error Wattmeter N396 device under the influence of an external uniform magnetic field induction 0.5 mT formed AC sinusoidal time-varying frequency of 50 Hz is equal to ± 0,5% of full scale range.
The limit of additional error Wattmeter N396 device to measure and record the measured value caused by a deviation from the normal frequency by ± 10%, equal to ± 1,5% of full scale range. The limit of additional error device to measure and record the measured value, caused by the changing position of the device from its normal position in any direction by ± 5 ° is ± 1,5% of full scale range.
The limit of additional error on the measurement and recording of measured values ​​caused by the deviation from the nominal voltage ± 20%, at a constant value of the measured power is equal to ± 1,5% of full scale range.
The limit of additional error on the measurement and recording of measured values ​​caused by the influence of the change of power factor, expressed as a percentage of the final value of the measuring range is equal to ± 1,5% at normal frequency; ± 3% at frequencies of 45-55 Hz.
Failure to return the instrument writing device Wattmeter N396 to the zero line record of 1.5 mm. The discrepancy between the zero line indicated on the chart tape, timer, with a line of records obtained when the pointer to the zero mark of the scale, not more than 0.75 mm.
The line width of recording up to 0.7 mm. Warm-up time 15 min. Write the results produced in ink on the ribbon diagram in rectangular coordinates. Working width of the chart tape - 100 mm. Ink, contains ink tank provides a continuous record of the testimony on the chart tape for at least 30 days.
Diagram for the drive belt used synchronous motor powered by an AC 50 Hz 220 V. On the customer equipment export performance can be made ​​with the engine power from the AC with a frequency of 60 Hz.
Devices have a six-speed movement chart tape 20, 60, 180, 600, 1800, 5400 mm / h, which are set by changing a couple of gears.
Insulation between the housing unit and all isolated from the case of electric circuits (excluding circuit timer) stand for 1 min test voltage AC 50 Hz, which is the effective value of 2 kV. Insulation between the housing unit and isolated from the external electric circuit timer stand for 1 min test voltage AC 50 Hz, RMS is 0.5 kV.
The insulation resistance between the case and isolated from the DC of any electrical appliance chain Wattmeter N396 in normal application of 40 MW. Own consumption of series and parallel circuits device to be included in current transformers and voltage at rated current and voltage and frequency of 50 Hz, less than 10 VA.
Overall dimensions 160h172h360 mm. Flange size 160x160 mm. Weight of the device does not exceed 7.5 kg.
