FAQ
Q: What is the IP rating of UniGear ZS1?
A:
UniGear ZS1 has an IP4X rating per IEC 62271-200, protecting against solids ≥1mm (e.g., dust) in indoor environments. Liquid ingress protection isn’t rated; avoid direct water exposure.
Q: What is the heat dissipation of UniGear ZS1?
A:
UniGear ZS1's heat dissipation complies with IEC 62271, achieving ≤65K temperature rise at rated current via optimized airflow and conductive materials (e.g., galvanized steel). Ensures stable operation under full load.

What is reactive power measurement?
The power which exists in the circuit when the voltage and current are out of phase to each other, such type of power is known as the reactive power. The formula measures the reactive power in the circuitReactive Power Measurement & VarmetersReactive power measurement is critical as it indicates circuit power loss: low reactive power worsens load power factor, increasing system losses.

How to Design and Install a Solar PV System?
Design and Installation of Solar PV SystemsModern society relies on energy for daily needs like industry, heating, transport, and agriculture, mostly met by non-renewable sources (coal, oil, gas). However, these cause environmental harm, are unevenly distributed, and face price volatility due to limited reserves—driving demand for renewable energy.Solar energy, abundant and capable of meeting global needs, stands out. Standalone PV systems (Fig 1) offer energy independence from utilities.

What are the common faults that occur when low-voltage current transformers are combined with other power equipment?
Low-voltage current transformers, as indispensable measurement and protection devices in power systems, often encounter various faults when used in combination with other power equipment due to environmental factors, equipment linkage issues, and improper installation and maintenance. These faults not only affect the normal operation of power equipment but may also endanger personal safety. Therefore, it is necessary to gain an in-depth understanding of fault types, judgment methods, and prevent
