Current error and phase error limits	Accuracy Class	Current error ±(%)				phase error(′)
		In the following currents				In the following currents
		0.01In		≥0.05In		0.01In	0.05In		0.2In	1In		2In		3In	Imax
	0.1 Class	0.2		0.1		15	8		5	5		5		5	5
	0.2 Class	0.4		0.2		30	15		10	10		10		10	10
	Note: When current is 0.2In~Imax, phase error(δe ) is the average of δmax and
	δmin;When current is i, the phase error of i is the difference of betweenδi  and δe. (δi=δi-δe).
	When currents is 15.9A, The electric energy measurement error introduced by current transformers  is less than 3%
