Meter load economizer circuit diagram

This is an application circuit of the device as illustrated in principle. In the meter, the voltage and current coils are connected to the power line, regardless of whether a load is connected. The voltage coil consistently draws power, allowing the electrical circuit to function effectively. This setup addresses issues that may arise when the current in the load circuit (RL) experiences a surge, causing the voltage coil to activate instantaneously without impacting the electricity metering. When the load (RL) is disconnected, the current in the voltage coil is interrupted, resulting in no-load losses.

The circuit described involves a meter designed to measure electrical parameters through voltage and current coils interfaced with a power line. The configuration ensures that the voltage coil remains energized, permitting continuous operation of the measurement system. This is crucial for accurate readings, as it allows the device to capture fluctuations in voltage without interruption.

When the load (RL) experiences sudden changes, such as a surge or a disconnection, the circuit is designed to respond dynamically. The current flowing through the load can cause the voltage coil to activate rapidly. This feature is essential for maintaining accurate metering under varying load conditions, as it prevents erroneous measurements that could arise from transient conditions.

Moreover, when the load is disconnected, the circuit is designed to cut off the current to the voltage coil, effectively eliminating no-load losses. This characteristic enhances the efficiency of the system by minimizing energy wastage when the load is not present. The design prioritizes both functionality and efficiency, ensuring that the meter operates optimally across a range of load conditions.

Overall, this application circuit exemplifies a robust approach to electrical measurement, integrating responsive features that enhance accuracy while reducing unnecessary power consumption.Application circuit of the device as shown in principle.
