1. Introduction
Flexible Coil Large Current Clamp Meter
is designed and manufactured for field testing of AC
large current. Widely used in electric power, communications, meteorology, railway, oil field,
construction, measurement, scientific research and teaching units, industrial and mining
enterprises and other fields. Especially suitable for the flat cable dense place, current test of
transformer grounding core , thick wire and cable, relay protection, silicon controlled rectifier,
frequency conversion speed regulation, semiconductor switch, power electronic conversion
equipment, arc welding and other industrial environment with serious signal distortion.
Flexible current clamp sensor
, Rogowski Coil, adopts advanced Rogowski Coil technology,
which is a loop coil uniformly wound on non-ferromagnetic materials, with no hysteresis effect,
almost zero phase error, no magnetic saturation, high linearity and strong anti-interference ability.
The output signal is the differential of the current with respect to time. By integrating the output
voltage signal, the input current can be truly restored. The measured current ranges from
milliamperes up to ten thousands of amperes. Flexible coil without any exposed metal conductor,
non-contact measurement, safe and reliable. Small size, light weight, soft and flexible, suitable for
narrow environment and flat cable dense places. High measurement accuracy, strong reliability,
wide response frequency band, the user can customize the coil length according to demand.
The meter has the functions of peak hold, data hold and data storage etc., convenient to use,
which is an essential tool for electrical safety inspection
