us Electricity Meter
The SDM630MCT-Modbus Electricity Usage Monitor is a powerful tool for monitoring and managing your single/three-phase electrical usage. Featuring an easy-to-read digital backlit LCD display, this device provides clear data visibility day and night. It can be easily connected to other devices via its Modbus RS485 communication feature. In addition, it is MID-certified, indicating our pursuit to provide products of the highest standard. With the ability to measure voltage, frequency (Hz), current (A), power (KW/kVA/kVAr), import, export and total energy (kWH/kVArh) accurately and efficiently, this monitor helps you identify areas where energy consumption can be reduced – allowing for maximum energy-saving potential and cost savings.

Purpose of CT Meter?
CT Operated Meters are used extensively for measuring current and monitoring the operation of the power grid. Along with voltage leads, revenue-grade CTs drive the electrical utility’s watt-hour meter on virtually every building with three-phase service and single-phase services greater than 100 amps. The CT is typically described by its current ratio from primary to secondary. Often, multiple CTs are installed as a “stack” for various uses. For example, protection devices and revenue metering may use separate CTs to provide isolation between metering and protection circuits and allows current transformers with different characteristics (accuracy, overload performance) to be used for the devices.
(Other Terms for CT are, current transformer, instruments transformer, folding converter, conversion transducer).
