Installation Instructions for Wireless Temperature Sensors and Data Collectors

Installation Instructions for the KSTC194K-8B LCD Smart Control Wireless Temperature Sensor and Receiver:

Application Environment

Temperature monitoring of equipment such as high-voltage switchgear contacts and terminals, disconnect switches, high-voltage cable joints, dry-type transformers, and low-voltage high-current switchgear.

Temperature Emission and Acquisition

Taking into account electrical insulation and live‑part isolation, we have adopted a newly developed wireless temperature‑sensing and data‑acquisition system, as shown in the figure below.
Each set of isolating disconnect switches (phases A, B, and C) consists of three temperature transmitters and one receiving temperature data collector. The temperature of each phase is measured by a sensor, the data are transmitted by the transmitter, and then collected by the receiving temperature data collector; a single receiving temperature box can accommodate 1 to 12 transmitting temperature signals.
Note: The receiver must be placed in the same space as the transmitting module to prevent signal loss.

Sensor installation method

Passive Wireless Temperature Sensor
Install the device at locations where temperature monitoring is required (e.g., moving contacts). One temperature sensor should be installed on each of phases A, B, and C, as shown in the figure below.

Active wireless sensor
Secure the device to the location requiring monitoring (e.g., busbar), installing one sensor on each of phases A, B, and C, and ensure it is firmly fastened. See the figure below:

Low Voltage Power Capacitor

Low-voltage dry-type shunt capacitors are energy‑saving devices used for power factor correction in low‑voltage power systems operating at 50 Hz or 60 Hz. They reduce reactive power losses and improve voltage quality. The KD‑H dry‑type eco‑friendly capacitor is manufactured using advanced German technology in a Class 100 cleanroom environment. Under vacuum conditions of 10–3 bar, the components are heated while protective gas is injected. This process effectively removes air and moisture from within the capacitor, preventing electrode oxidation and localized discharge. Following this sophisticated manufacturing sequence and rigorous factory acceptance testing and quality assessments, the capacitors achieve exceptional stability and an extended service life. Depending on the application, they are available in single‑phase and three‑phase configurations.

Original Imported Low Voltage Capacitor

The original imported MOKN series capacitors are highly popular in the Chinese market thanks to their proprietary technology. During production, these capacitors are filled with nitrogen (N2), and they incorporate a unique SINECUT grooving process along with a distinctive metal‑treatment technique. Moreover, their optimally positioned internal core ensures that the device’s capacitance remains stable even under the severe stress of high‑voltage AC surges and negative pressure conditions. This hallmark feature makes the MOKN series particularly well suited for applications involving controlled equivalent DC currents and surge protection.

Low Voltage Intelligent Capacitor

The KD‑Z series intelligent low‑voltage power capacitors are a next‑generation reactive power compensation device designed for 0.4 kV low‑voltage distribution networks, delivering high efficiency and energy savings, reducing line losses, and improving the power factor and power quality. They consist of an intelligent measurement and control unit, a synchronous switching circuit, a line protection unit, and low‑voltage power capacitors. These units replace conventional automatic reactive power compensation systems that rely on discrete components—such as smart controllers, fuses, composite switches or mechanical contactors, thermal relays, low‑voltage power capacitors, and indicator lights—wired together inside and on the surface of switchgear cabinets. By eliminating the bulky, unwieldy design of traditional systems, this new generation of low‑voltage reactive power compensation equipment offers superior compensation performance, a more compact footprint, lower power consumption, reduced costs, greater cost savings, enhanced flexibility in application, simplified maintenance, extended service life, and higher reliability, thereby meeting the increasingly stringent requirements of modern power grids for reactive power management.

Low-Voltage Anti-harmonicIntelligent Power Capacitor

The KD‑ZLK harmonic‑suppression intelligent power capacitor is equipped with a custom segmented LCD display that provides real-time readings of three-phase bus voltage, three-phase bus current, three-phase power factor, frequency, the number of capacitor banks and their switching status, active power, reactive power, total harmonic distortion of voltage, and capacitor temperature.
