Understanding the 3 Phase Energy Meter with CT In industrial and commercial electrical installations, monitoring power consumption accurately is crucial. One of the most common setups used for this purpose is the 3 Phase Energy Meter with CT (Current Transformer). This configuration is ideal for systems with high current loads, where direct connection to the

If you’ve ever worked in industrial automation, energy monitoring, or building management systems, chances are you’ve heard of the MODBUS Protocol. Developed in 1979 by Modicon (now Schneider Electric), the MODBUS protocol is one of the most widely used communication protocols for connecting electronic devices and field instruments with controllers, PLCs, HMIs, and SCADA systems.

How to calculate CT ratio in Multi-Function Meter (MFMs) is an important setting for electrical characteristics such as current, voltage, power factor, and energy usage in commercial and industrial electrical installations. However, it is essential to set the correct Current Transformer (CT) ratio for MFMs to provide accurate readings. To effectively Calculate CT ratio, one
