1. Dry-type Current Transformers with Protective Class(LGB)

2. Instruction

The dry-type current transformer, assemblying by a bushing-type primary winding and secondary winding(s).Possessing those advantages of light frame, oil-free, gas-free, porcelain-free, fire-proof and explosion-proof etc, used for current measurement and relay protection in the power system with the rated voltage of 35kV.

3. Service Conditions

a. Ambient air temperature: maximum 40℃, minimum -40℃, average value of the ambient air temperature does not exceed 30℃ measured during a period of 24h.

b. Altitude: The altitude does not exceed 1000m (this is the routine requirement, if there is any different

requirement, we can provide the products with 2000m, 3000m, 4000m or 5000m altitude according to the clients' requriments).

c. The average value of the relative humidity does not exceed 95% at 25℃ measured during a period of one month.

d. The maximum wind speed does not exceed 34m/s.

e. Eerthquake intensity does not exceed 8 degree.

f. There have to be no gas that may seriously affect the insulation and conductive ability of electric  equipments, steam, ash, salt, chemical deposit, pollution and corrosive or explosive material.

4.Main Technical Parameters1.1 Rated primary current is 50A~4000A.

1.2 Rated secondary current is 5A or 1A.

1.3 Rated frequency is 50Hz or 60Hz.

1.4 Rated output: 20VA~40VA (If any other rated output required, We can satisfy it.)

1.5 Accuracy classes and their combinations: Steady accuracy classes are 0.2S, 0.2, 0.5S, 0.5, 5P, 10P, PR and PX;

     transient accuracy classes are TPS, TPX, TPY and TPZ. There are 1~6 pcs secondary winding(s) in a CT.

1.6 Instrument security factor (FS) of measuring class is 5 or 10.

1.7 Accuracy limit factor (ALF) of protective class is 5, 10, 15, 20, 30 or 40.

1.8 Rated continuous thermal current Icth is 1.2In.

For rated short-time thermal current Ith (r.m.s.) and rated dynamic current Idyn (peak), please see Table 2.
