Q1: What is a clamp-on current transformer?
A1: Clamp-type current transformer is a kind of detection device, that can feel the information of the measured current, and can detect the felt information. Clamp AC transformers according to a certain law into a certain standard need to meet the electrical signal or other required forms of information output, in order to meet the requirements of information transmission, processing, storage, display, recording, and control. For example, switching power supply, hard switch, soft switch, etc.
Q2: What equipment can be used with a clamp-on current transformer?
A2: Clamp-on current transformers can be used with multimeters (mA level current grade), oscilloscopes, and other instruments, and clamp-on AC transformers can also be used as current probes.
Q3: What are the advantages of sisco clamp-on current transformer?
A3: sisco clamp-on current transformer is a precision current transformer, which is specially designed for power field measurement and metering use characteristics. The clamp-on current transformer is made of high permeability material, high precision, strong anti-interference ability, etc. When using the clamp-on current transformer can be directly clamped on the bus bar or bus bar without cutting off the line power outage its use is very convenient.
Tips: How long is the calibration cycle of the current transformer?
- Measurement and standard instruments and special requirements of the current transformer calibration cycle for every two years.
- The general instrument transformer verification cycle is once every four years
- The inspection items of the instrument transformer are: checking the polarity of primary and secondary coils, measuring the ratio and angle difference, measuring insulation resistance, dielectric loss, and voltage test.
