Table 1 Rated primary and secondary currents, accuracy levels, and corresponding secondary output capacities

Primary current (A)	Secondary output	Rated capacity (VA)	accuracy level	Maximum Capacity (VA)
100~200	1A or 5A	two point five	±0.5%	five
300~400		five	zero point five	ten
500~750		five	zero point two	twenty
100~750	10V		0.2~0.5

Installation steps:
1. Fix the current transformer and its base on the crossbar, and install the transformer protection box vertically to avoid water ingress or storage inside the box.
2. Determine the position of the current transformer clamp wire, wrap the high-voltage wire at this position with insulating tape, with a length of about 390 millimeters and a diameter of about 22 millimeters after winding.
3. Wrap the wire around the winding part with an insulating sleeve, and then wrap a layer of insulating tape (about 1mm) outside the sleeve
4. Place the overhead wire with conduit installed in the center of the current transformer, symmetrically in front and behind.
5. Apply silicone evenly on the joint surface of the upper and lower halves of the current transformer, align and fix them together.
6. Wrap the metal braided wire on the CT with a primary wire using metal binding wire to maintain equipotential.
7. Place the protective cover over the CT and fasten 10 buttons.
Attention: Install a lightning arrester next to the LZK-10W current transformer to prevent lightning strikes.
