current_phases (Optional): The number of phases the meter has, 2 or, 3 Then, the meter auto-calculates the full set of phase-to-phase voltages based on the phase-to-ground measurements. gain_pga (Optional, string): The gain for the CT clamp, 2X for 100A, 4X for 100A - 200A. Use this sensor & be alerted of about imbalances or power faults. If you have a meter with a current clamp, you can also check the current in each phase to verify that they are well balanced. Building owners and machine operators count on Monnits ALTA Wireless 3-Phase AC Current Meters to identify irregularities with equipment and power supplies, preventing minor issues from becoming costly problems. The ATM90E32 IC can measure up to three AC voltages although typically only one However, in applications using potential transformers (PTs), the secondary of the PT can be wire to provide a reference point. For the add-on boards a jumper can be selected for each CS pin, but default to 0 and 16. line_frequency (Required, string): The AC line frequency of the supply voltage. Three-phase motors are generally well balanced, but other loads may not be. These clamps come with a dual-display screen allowing simultaneous measurement and display of voltage and amperage. The load may be imbalanced.
|, Monitoring Only One or Two of Three Phases, LonWorks Plug-Ins, Network Software, and XIF Files. Now the Clamp is in line-to-line mode and, Position the clamp jaw around the first conductor. For the best experience on our site, be sure to turn on Javascript in your browser.
/4-wire electrical systems less than 600A. Well help you select the right product for your needs. The device comes in a sealed box making it moisture-proof and withstands extreme conditions.
Wait for the measurement on the screen to settle.
Therefore, in this application, the WNB and WNC series meters can be used with only two CTs. sensor using calculation: New gain_ct = (your current reading / ESPHome current reading) * existing gain_ct value. Remotely monitor power consumption to track motor health or power system faults. Sensor. Remotely monitoring your business with a 150 Amp AC Current Meter opens up many possibilities. Identify when a fuse is blown on a phase, resulting in phase loss. current on the selected phase. If your load is actually multiple loads (like monitoring the three-phase service to the floor of a building), then there is a high likelihood of imbalance. small. Update gain_voltage for all phases in your ESPHome yaml, recompile and upload. All rights reserved. Push MIN MAX again to show the L1 measurement. Same options as 1st phase. It is possible that the two identical CT current sensors will have different But it does not mean all meters can take advantage of this. L1, L2, and L3 (or Line 1, Line 2, and Line 3) are commonly used naming conventions for the wires in three-phase alternating current (AC) systems. with solar pv installations). WILL ONLY WORK IN VUE ENERGY MONITOR PORTS (not meant for use in 50A Vue Expansion Module ports), Need more information about Emporia? To adjust the sensor use the calculation: New gain_voltage = (your voltage reading / ESPHome voltage reading) * existing gain_voltage value. The screen will turn green, beep, and, Move the clamp jaw to the second conductor within 10 seconds. For the 6 channel meter main board, this will always be 5 and 4. When the L1-L2-L3 measurements are complete, use the clamp to calculate the total voltage between each pair of conductors: While in the line-to-line mode, you can review each line-to-ground measurement: To review L1-L2-L3 measurements, continue to push the MIN MAX button and scroll through the measurements. For balanced three-phase, four-wire (wye) circuits, each CT will measure exactly one-third of the total current. Push MIN MAX again to show the L3 measurement. frequency (Optional): Use the frequenycy value calculated by the meter. ESPHome. A new version has been release since you last visited this page: 2022.6.2 .
All options from Push MIN MAX once: screen shows the total voltage between L1 and L2. This sensor is commonly found in CircuitSetup 2 and 6 channel energy meters. CircuitSetup Expandable 6 Channel ESP32 Energy Meter Main Board.. # Example configuration entry for split single phase meter, # Example CircuitSetup 6-channel without jumpers jp9-jp11 joined or < meter v1.4. Defaults to 3. update_interval (Optional, Time): The interval to check the sensor. This sensor needs calibration to show correct values. Subscribe to our newsletters to get the latest updates delivered conveniently to your inbox. The CircuitSetup 6-Channel Energy Monitor can read 6 current channels and 2 voltage channels at a time, this board has two ATM90E32 ICs and requires two sensors to be configured in ESPHome. You will hear a beep and. For for a more accurate calibration use a Does not work with 3-phase/3-wire systems..
The WND series meters can measure 3-phase 3-wire delta, 4-wire delta, and corner grounded delta services using only two CTs.
