一、 功能特點及用途
1、 單機可以完成1000kVA以下的配電變壓器全電流下的負載試驗；在三分之一額定電流下可完成2500kVA以下的配電變壓器的負載試驗（在三分之一的額定電流下，儀器可換算到額定電流下的負載損耗參數。）。
2、 單機可以完成6300kVA以下的配電變壓器的容量試驗和容量檢測。自帶的試驗電源一次充電可以完成100臺2500kVA配電變壓器容量的試驗。根據變壓器空載損耗試驗結果，可以判斷出變壓器的型號。
3、 240*120超大藍屏液晶顯示器，中文操作菜單，高速打印機打印試驗結果和歷史記錄。
4、 以高性能的處理器作為控制和運算的核心，采樣速度快，數據的穩定性好。
5、 可外接電壓互感器和電流互感器可拓寬儀器的測量范圍。
6、 電流、電壓采樣不經過互感器直接采樣，大大提高了儀器的測量范圍和測量精度，優于市面大多數同類儀器。
7、 儀器的體積小、重量輕、便于攜帶。適用于試驗室與現場測試和操作規程。
8、 HRKFR變壓器空載負載及容量分析綜合測試儀是按照并符合 JB／T501－91《電力變壓器試驗導則》和GB1094－96《電力變壓器》的技術標準要求研發設計生產的。

1） Functions, features and use
A. Single machine can complete under 1000kVA distribution
transformers and full-electric flow load test; About a third
of the rated power flow can be completed under 2500kVA distribution
transformers load test(About a third of the rated flow,
electric instrument can be converted to the rated flow load
loss electric parameters).
B. Single machine can complete under 6300kVA distribution
transformer capacity experiment and capacity test. Self-contained
test power can charge 100 sets of 2500kVA distribution transformer
capacity test in one time. According to the experiment results,
transformer no-load loss can judge the transformer models.
C. 240 * 120 large blue LCD, Chinese operation menu, high-speed
printers print test results, and the historical record.
D. With high-performance processor as the core of control
and operation. Sampling speed. The data stability is satisfactory.
E. It can external voltage transformer and current transformer
can broaden instrument measurement range.
F. Current, voltage transformer, sampling don't pass through
mutual inductor but take samples directly, greatly improved
instrument measurement range and accuracy of measurement,
better than most of the similar instruments in the market.
G. They are small, light and easy to carry, and are suitable
for laboratory and field test and operation procedures.
H. HRKFR transformer no-load loading and capacity of comprehensive
analysis instrument is according to JB／T501－91(Power Transformer
Test Guidelines) and GB1094－96 <Power Transformer>.
