Fault Indicator EKL-4, designed specifically for efficient power restoration. Its compact and portable size, powerful auxiliary functions, and excellent work efficiency make it a reliable assistant for power workers. This indicator is not only suitable for voltage levels of 6-36KV, but also has a suitable load capacity of 0-600A and a wire current carrying capacity of 1 ≤ 1000A. Its response time is fast, static power consumption is extremely low, and the reset time is optional, with a maximum of 4000 actions. In addition, the design of the opening size of 92 * 44mm takes into account actual installation requirements.

Reactors, also known as inductors, are widely used in circuits. Due to the electromagnetic induction effect, there is a certain degree of inductance in the circuit, which can prevent changes in current. When a conductor is energized, it will generate a magnetic field within a certain spatial range it occupies, so all conductors that can carry current have a general sense of inductance. However, the inductance of an electrified long straight conductor is relatively small, and the magnetic field generated is not strong. Therefore, the actual reactor is a hollow core reactor in which the wire is wound into a solenoid form; Sometimes, in order to increase the inductance of this solenoid, an iron core is inserted into the solenoid, known as an iron core reactor. Reactance is divided into inductive reactance and capacitive reactance. A more scientific classification is that inductive reactance (inductor) and capacitive reactance (capacitor) are collectively referred to as reactors. However, due to the existence of inductors in the past, which were called reactors, capacitors are now referred to as capacitive reactance, while reactors specifically refer to inductors.
