Energy Meter Shunts
allows users to measure the current flowing through the load. These shunts are commonly made of high-precision manganin resistors. These resistors divide the current flowing through the load into two parts: one part is an ammeter, which measures the current flowing in one direction, and the other part is a shunt resistor. These shunts allow users to measure a wide range of amperages. The shunt can be wired in parallel or in series with the load.
One type of shunt is the five-terminal shunt, which is used for measuring the current flowing in a line. This type of shunt has a resistance of 0.3 mOhms and is often used in the measurement of current. Besides energy meters, shunts can be used for other applications, including solar inverters and process monitoring.
Another type of shunt is a current sensor. This type of shunt measures the current by monitoring the change in voltage. A current shunt is commonly made of manganin resistors, which are excellent for accurate current measurements. Their low-temperature coefficient of resistance makes them highly stable.
In an electronic energy meter, the current flow is measured by means of an electrical shunt. This shunt allows the energy meter to accurately determine the level of current flowing through the system. The resistance must be set so that it matches the drop in voltage. Some meters use precision current shunts, allowing them to measure DC current and Watts.
The shunt resistor should be placed as close to the ground as possible. This will protect the ammeter from common mode voltage, which could damage the instrument. Leakage currents bypass the shunt and may be undetected by the meter. For this reason, an isolation amplifier is necessary for ungrounded leg shunts.
A shunt is also a good choice for circuits that have a high frequency. The shunt should protect the device from the high voltage, which would short out the device. This way, it will direct the high current flowing through the shunt to the ground. This is a safe way to measure large currents.
SHUNT is precision element for the energy meter, adopts the advance technical of plane jointing.
