What is a high current transformer? High Current Transformers are designed to elevate and check the temperature of conductors at high current levels, in order to simulate the current loading conditions found in electrical circuits.
What is a high current transformer?
High Current Transformers are designed to elevate and check the temperature of conductors at high current levels, in order to simulate the current loading conditions found in electrical circuits. High Current Transformers are designed as an open type transformer.

What is a Class 1 current transformer?
The class designation is an approximate measure of the CT’s accuracy. The ratio (primary to secondary current) error of a Class 1 CT is 1% at rated current; the ratio error of a Class 0.5 CT is 0.5% or less. Errors in phase are also important, especially in power measuring circuits.
What is the current transformer 1 point?
A current transformer is a device that is used for the transformation of current from a higher value into a proportionate current to a lower value. The ratio of the primary current and the secondary current is known as a current transformer ratio of the circuit.
What is knee point voltage?
Knee point voltage is nothing but a magnitude of the saturation limit of the current transformer. As per IEC, the Knee Point Voltage of a Current Transformer is defined as the voltage at which 10 % increase in voltage of CT secondary results in 50 % increase in secondary current.
Why CT is used in energy meter?
All electric energy used passes through the meter. These meters are designed to be used on services under 200 amperes. The CT transforms the primary current of the line conductor to a smaller, more easily managed current that is carried to the meter which is directly proportional to the primary current.
What is CT ratio in transformer?
Ratio. The CT ratio is the ratio of primary current input to secondary current output at full load. For example, a CT with a ratio of 300:5 is rated for 300 primary amps at full load and will produce 5 amps of secondary current when 300 amps flow through the primary.
What is knee point value?
What is knee point CT?
The point where CT saturates also known as the knee point, which according to IEC, knee point is the voltage at which a 10% increase in voltage of CT secondary results in a 50% increase in secondary current.
What is the current frequency of a transformer?
Current transformere ratio can select 300/5A, 500/5A, 800/5A and 1500/5A, rated frequency 50Hz and 60Hz are avaliable, accuracy classes can choose 1, 0.5, 0.5S, 0.2 and 0.2S. Low price and manufacturer direct sale.
How does a transformer convert high current to low current?
It converts the high current to a low current by ratio, its primary end is connected with the primary system, while the secondary end is connected with the measuring instrument and relay protection. How can we install your current transformer? How can we install your current transformer?
What’s the current ratio of an AC transformer?
AC current transformer accuracy classes can choose 1, 0.5, 0.5S, 0.2, or 0.2S, current ratio 300:5A, 600:5A, 800:5A and 1500:5A are optional, low cost and free shipping. Note: The installation method of current transformer can be fixed by busbar and fixed by the bottom plate, suitable for installation in any direction.
What kind of winding does a current transformer have?
Current transformer consists of closed iron core and winding. It has few primary winding that are connected in series in the current circuit under measurement; however, it has many secondary winding, which are connected in series in the measuring instrument and protection circuits.
