Conditions for normal operating environment:

  • Ambient air temperature: -5℃ ~+40℃  and the average temperature should not exceed +35℃  in 24h.

  • Air condition: With clean air. Relative humidity should not exceed 50% at +40℃  . Higher relative humidity is allowed at lower temperature. Ex. 90% at +20℃ . But in view of the temperature change, it is possible that moderate dews will produce casually. 

  •  Altitude above sea level should not exceed 2000M. 

  • The device is suitable to the transportation and store with following temperature :-25℃  ~+55℃  , in short time (within 24h) it reaches +70℃  . Under the limiting temperature, device should not suffer damage that can' t recover, and it can works normally under normal conditions.

  • If the above operating conditions not meet user's demand. Consult with manufactory.

  • Technical agreement should be signed additionally if the device is used for marine petrol drill taken platform and nuclear power station.

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. Varmeters (volt-ampere reactive meters) measure reactive power and are categorized by circuit phases:Single

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
