Taier Certification Center Co., Ltd. (TLC for short), formerly known as "Theer Certification Center", is a voluntary product specialized in the information and communication industry fully funded and established by the China Academy of Information and Communications Technology (formerly the Telecommunications Research Institute of the Ministry of Industry and Information Technology). The certification body also carries out CCC, quality management system, environmental management system, occupational health and safety management system, service certification and information security management system business.

Unlike other certifications, in the Thiel certification of the unit, the requirements for capacitive loads have been added. Capacitive load bank detection of units The following two methods can be used to detect the capacitive load bank of units:

a) The resistive load is configured according to 100% of the rated active power output of the unit. And configure the phase according to the power factor leading (capacitive) 0.95

should be capacitive load. The unit runs for 1h under rated conditions. Record power, voltage, current, power factor, frequency, diesel engine cooling water (or wind) temperature, oil pressure and generator winding temperature every 30 minutes.

b) The capacitive load is configured according to 20% of the apparent power value of the unit. The active power of the unit starts from 20% of the full load and increases every half hour.

Increase resistive load to 40%, 60%, 80% and record power, voltage, current, power factor, frequency, diesel cooling outlet water (or wind) temperature, oil pressure and generator winding temperature in each state.

If your unit and power supply are entering the communication industry, then it is necessary to pay attention to this requirement.

In order to solve this problem, the first electrical test, launched a high-voltage resistance-capacitive load bank:
