5. Frequently Asked Questions (FAQ)
5.1 What is the difference between this test power distribution transformer and ordinary outdoor oil-immersed transformers?
The biggest advantage of the Three Phase Outdoor Oil-immersed Test Power Distribution Transformer is its dual functional design of power distribution and electrical testing. Ordinary outdoor oil-immersed transformers only support single daily power distribution function and cannot meet professional power equipment testing and parameter calibration needs. This upgraded model maintains all stable power distribution performance of conventional transformers, while adding high-precision voltage simulation, load state simulation and power performance detection functions, which can be used for power engineering experiments and equipment testing. In addition, it has higher voltage output accuracy, stronger overload test resistance and wider capacity coverage (50KVA-3000KVA), making it more suitable for professional power engineering scenarios than ordinary single-function distribution transformers.
5.2 How to select the appropriate capacity between 50KVA and 3000KVA for practical use?
Capacity selection needs to be determined according to actual power distribution load and test project requirements. The 50KVA three-phase outdoor transformer is suitable for small-scale scenarios, including rural light industrial power distribution, small temporary engineering power supply and low-power electrical equipment routine testing. Medium transitional capacities apply to conventional industrial workshop power supply and daily power parameter debugging. The 3000KVA large-capacity oil-immersed transformer is tailored for heavy-load scenarios such as large industrial park centralized power supply, large power equipment performance testing and new energy station supporting power distribution. It is recommended to reserve 15%-20% load margin for both power distribution and testing work to avoid long-term overload operation and extend equipment service life.
