The power table is also called Watt.A instrument that measures electricity.Electricity includes power power, powerless power, and view power.When no special instructions are made, the power table generally refers to measuring instruments with power.
The purpose of the power table
Light power measurement: It is used to measure absolute light power or relative loss of light power through a section of optical fiber.In the optical fiber system, the measuring light power is the most basic, very much like a universal watch in electronics.In optical fiber measurement, the optical power meter is a commonly used table for heavy load.By measuring the absolute power of the transmitter or the light network, a light power meter can evaluate the performance of the optical end equipment.The combination of light power metering and stable light source can measure connection loss, test continuity, and help evaluate the quality of optical fiber link transmission.Electric product inspection test: The inverter power table is suitable for product inspection tests, energy efficiency evaluation and energy quality in the fields of electrical advancement, motor, wind turbine, pumps, wind power generation, rail transiters, frequency converters, special transformers, fluorescent lamps, LED lighting and other fieldsanalyze.
Power table model
The meaning of the power table: 1. Category code: D-Electric Table 2. Group code indicates phase line: D-single; S-three-phase and three lines; T-three-phase and four lines.Indicates the classification of use: D-multifunctional; S-electronic; x-unclear; y-prepaid; F-reinstation rate.
Usage of power table
① Select the range of the power table correctly.Select the range of the power table is to select the range and voltage range in the power table.When using, the current table in the power table should not be less than the load current, and the voltage range is not lower than the load voltage, and cannot be considered from the power range.For example, the two power tables are IA, 300V and 2A, 150V, respectively. From the calculation, it can be known that its power range is 30ow. If you want to measure the load power of 220V and the current of the current, you should use IA and 300V.Although the power table of 2A and 150V of 2A and 150V is greater than the load power, it cannot be used because the load voltage is higher than the voltage of 150V that the power table can withstand.Therefore, before the measurement power, the range of the power table should be selected according to the rated voltage of the load and the rated current.② Correctly connect the measurement line.The direction of the rotation moment of the electric measurement mechanism is related to the current direction of the current in the two coils. In order to prevent the pointer of the power table of the power table, the power surface current line is marked with the "·" end button to receive the positive extreme extreme of the power supply.The other end of the current coil is connected to the load, and the current coil is connected to the circuit in series.The end button of the power table voltage coil has the end button of the "·".
