在测量过程中，除要严格遵守电气安全规程和设备试验规程外，还要特别注意：

In the measurement process, in addition to strictly abide by the electrical safety regulations and equipment test procedures, but also pay special attention to:

１）在线圈温度稳定的情况下进行测量，要求变压器油箱上、下部的温度之差不超过３℃；

1) the temperature of the coil is stable, and the temperature difference between the upper and lower parts of the transformer oil tank is not more than 3 degrees centigrade;

2）由于变压器线圈存有电感，测量时的充电电流不太稳定，一定要在电流稳定后再计数，必要时需采取缩短充电时间的措施

2) due to the inductance of the transformer coil, the charging current is not stable when measuring, must be counted after the current is stable, and if necessary, take measures to shorten the charging time

3）尽量减少试验回路中的导线接触电阻，运行中的变压器分接头常受油膜等污物的影响使其接触不良，一般需切换数次后再测量，以免造成判别错误。

3) try to reduce the wire contact resistance in the test circuit, the transformer tap is often affected by the oil film and other dirt, make it contact bad, generally need to switch several times after measurement, so as to avoid discrimination error.

4）测量变压器低压侧时，所有人员应与高压侧保持适当安全距离。

4) when measuring the low voltage side of the transformer, all personnel should keep the safe distance from the high voltage side.

5）仪器在运输、储存及工作中应避免强烈震动、阳光直射和磁场的影响，存放保管仪器时，应注意环境温度和湿度，应放在干燥、通风、无腐蚀气体的地方为宜，不得受潮、雨淋、暴晒，使用时轻拿、轻放，不得跌落。

5) instruments in the transport, storage and work should avoid direct sunlight and strong vibration, the influence of the magnetic field, storage equipment, should pay attention to the environment temperature and humidity should be kept in dry, ventilated, non corrosive gases where appropriate, not damp, rain exposure, use light, light, no drop.
