The description of meter ЭК0200 operation.


The study is based on measurement of the meter ЭК0200 real short-circuit current and contact voltage measurement unit during a short circuit, implemented unit for short time-limited circuits. A single-phase short circuit is produced via the thyristor.

To eliminate errors from transients and conductors magnetization, measurements are performed in two cycles with alternating direction of the short current.

During the first measure. the thyristor switches to maximum negative half cycle of the voltage (270 electrical degrees) the phase shift between the current and voltage in the circuit of "zero-phase". During the second cycle, the incorporation of thyristor takes place considering the phase determined in the first cycle and in the opposite polarity to avoid transient bias and steel pipes, if the conductors are located in the pipes.
