Milesight CT101/CT103/CT305/CT315 - optimal solutions for efficient energy management
Smart management of energy consumption requires the right equipment. With the new Devices from Milesight IoT, large-scale implementation of power metering has never been easier. In the following post, we describe the implementation, operation and advantages of the LoRaWAN CT Series devices.
LoRaWAN CT - the future of energy management
The smart current transformer is a device that supports the LoRaWAN protocol for communication. The device features innovative, non-invasive and fast installation (it is inserted non-invasively on the monitored cable). The current transformer accurately estimates energy consumption at a sampling rate of up to 3.3 kHz and calculates cumulative amp-hours every second, helping identify energy consumption patterns to determine at what times and where energy consumption is highest, etc. In addition, smart current transformers are ideal for checking for power failures or whether the machine connected to the cable is working properly.
Self-powered - meaning no batteries, no problems
The CT10x is designed to draw power directly from the circuit being measured, this eliminates the limitations of batteries while providing continuous power to the device without problems. There is also an option to power this device via USB-C.
Non-invasive Installation
Non-invasive installation with an open design, ensures no damage to circuits or power interruptions during equipment deployment.
High accuracy
High accuracy - supports a frequency of 3.3 kHz, which provides a very good level of measurement.
Smart reports
Reporting of current values and accumulated amp-hours occurs in the hardware-dedicated Milesight IoT Cloud app. There is also nothing preventing the use of an external application. LoRaWAN is an open communication protocol that will allow seamless integration with any customer platform.
Cloud platform for management
Support for Milesight's cloud platform with formula algorithms to convert Ah to Wh data, enables customers to monitor energy changes and detect anomalies. The Milesight IoT Cloud platform also supports custom feeds so that energy consumption can be converted to carbon emissions when needed.
Monitoring of carbon dioxide emissions
With the increasing complexity of carbon emission laws and regulations in Poland and the EU, it is becoming increasingly popular for companies to measure their own carbon emission levels. Milesight IoT Cloud supports a custom calculation function that can convert current CT-measured values into energy consumption and even carbon emissions.
Two types of device design - combined and detachable
By using two installation models, the device will fit into any space. The detachable design will allow the antenna to be brought out of the electrical box, for example, to increase the range of LoRaWAN signal propagation.
CT100 and CT300 series
The CT100 is designed for single-phase AC power suitable for construction and HVAC scenarios, while the CT300 is designed for three-phase AC power suitable for commercial and industrial applications. The products have four main applications:
Circuit monitoring - collecting current values and accumulated amp-hours.
Energy management - accurate monitoring of energy consumption, precise collection of consumption data.
Energy Modernization - CT Series can be quickly implemented and used.
Energy-saving solutions - in conjunction with the platform and software, perform data analysis using artificial intelligence algorithms to optimize energy consumption.
Monitor energy consumption trends - suitable for commercial buildings, factories, schools, hospitals and other buildings with high energy consumption. Installation in the position of a single live wire in the distribution box
Even more accurate monitoring of energy consumption
Milesight CT series devices use the T-RMS algorithm. RMS and T-RMS are different methods of calculating current waveforms. Both RMS and T-RMS use the root mean square to represent the current rms value.
The RMS calculation method applies only to sine waves, assumes that the waveform is a sine wave, and estimates the current rms value from an empirical value. The Milesight CT series uses the more accurate T-RMS root mean square algorithm, which is much closer to the actual value than the RMS method and applies to all waveforms.
Simply put, RMS can only detect the waveform shown on the left, while T-RMS can detect a waveform closer to reality (on the right) affected by noise. In addition, Milesight CT instruments boast an impressively high sampling rate of up to 3.3 kHz, outperforming other competitors in the market, guaranteeing unparalleled accuracy and detail.
Application together with the WS523 smart socket
WS52X is a smart portable outlet for energy efficiency that accurately measures voltage and power factor throughout a building. In smart building applications, one WS52X can be connected to multiple CT devices for more accurate and targeted energy saving programs.
CT provides more accurate data on accumulated currents, which can work well with WS52x. The use of CT + WS52X provides a complete calculation formula reflecting the energy consumption of a building and allows for the most effective reduction of energy consumption and improvement of energy use in a safe manner.
