Electronic energy meter voltage circuits

Electronic energy mcb circuit breaker loop and current loop is not an independent circuit, terminal end of the table without a voltage electric meter meter small hook, is conducive to tamper. Electronic energy meter current circuit is constituted manganese copper, the resistance value is low, Voltage stabilizer in the loop can not afford to divert traffic. Electronic meter counter with anti-down metering function, either forward or reverse current loop is connected, can be positive measure.
