What is a Smart Meter?

​Smart meter is a metering device that can measure electricity remotely through RS485 data transmission and terminal computer software management. Free automatic power off, timed power off, student apartment malignant load identification and other functions.

Three basic types of current transformer

Wound Current Transformer – The transformers primary winding is physically connected in series with the conductor that carries the measured current flowing in the circuit. The magnitude of the secondary current is dependent on the turns ratio of the transformer.

single-turn current transformer Core column type

Core column type: The primary coil is a copper column installed in the wall-penetrating magnetic sleeve, and the wall-penetrating The magnetic sleeve is the main connection between the primary coil and the secondary coil and the primary coil to the ground.

Parameters of double coil relays

Type: Double coil magnetic latch type (reverse polarity) Manual switch type Series : ADJH series Model: ADJH24112 Appearance size: 39×15×30.2(L×W×H)

Three key parameters of the shunt

The shunt used in the power battery PACK is essentially a resistor to detect the current value flowing. Since the current value is not easy to monitor, most of them are converted into voltage at present, that is, when the current passes, the resistor generates a voltage drop, and the voltage value is detected to calculate the passed current value, which is based on U=IR.
