Multi-function power meter can measure all common power parameters in three-phase power grid system with high precision: three-phase voltage, three-phase current, active power, reactive power, power factor, grid frequency, active energy, reactive energy, and Communication interface and power pulse output function. Let's take a look at the main points of the multi-function power meter wiring with the instrumentation world network.
Auxiliary power supply: Multi-function power meter has universal (AC/DC) switching power input interface. The working voltage of the instrument limit is AC/DC: 80-270V. Please ensure that the power supply is suitable for this series of products, to prevent damage. product.
It is recommended to install a 1A fuse on the side of the live line with AC power.
For areas with poor power quality, it is recommended to install a surge suppressor in the power circuit to prevent lightning strikes, as well as a fast burst suppressor.
Input signal: The multi-function power meter adopts the calculation method of each measurement channel to collect separately, which ensures the use is completely consistent and symmetrical. It has multiple wiring modes and is suitable for different load forms.
Description:
Voltage input: The input voltage should not be higher than the rated input voltage of the product (100V or 400V). Otherwise, the PT should be considered and a 1A fuse must be installed at the voltage input.
Current input: The standard rated input current is 5A. If it is greater than 5A, external CT should be used. If other instruments are connected to the CT, the wiring should be connected in series. Before removing the current input connection of the product, be sure to disconnect first. CT primary loop or short circuit secondary loop. It is recommended to use the terminal block, not directly connected to the CT, in order to facilitate disassembly.
Make sure that the input voltage and current are the same, the phase sequence is the same, and the direction is the same; otherwise, the value and symbol error will occur!! (Power and Energy)
The configuration of the meter input network is determined according to the number of CTs of the system. In the case of two CTs, the three-phase three-wire two-element method is selected; in the case of three CTs, the three-phase four-wire three-element method is selected. The input network NET set in the instrument wiring and instrument programming should be consistent with the wiring of the measured load, otherwise the voltage or power measured by the meter will be incorrect. Among the three-phase three-wire, the voltage is measured and displayed as the line voltage; and in the three-phase four-wire, the voltage measurement shows the phase voltage.
Installation tips:
1. On a fixed power distribution cabinet, select a suitable place to open a mounting hole with a hole size.
2. Take out the multi-function power meter and remove the fixing clip.
3. The multi-function power meter is installed in the meter hole of the power distribution cabinet.
4. Insert the clamp into the meter.
