1. Ambient temperature
The specification of the sensor will rule the ambient temperature range of the normal operation of the sensor, such as 40-85 degrees, which varies depending on the product model. It is advocated that the temperature range of the rules in the specification should not be exceeded, and the normal operating temperature range of the sensor should be exceeded, and the performance of some internal equipment will be degraded due to temperature characteristics, resulting in a decrease in accuracy, inaccurate output signal, or inability to operate. The sensor should be installed in a place with good ventilation and heat dissipation as much as possible, so as not to affect the measurement accuracy and life of the sensor due to excessive temperature.
2. Altitude
Usually the sensor is designed with altitude in mind, and the general condition is 2000 meters. However, it is not only suitable for the altitude below 2000 meters, if the altitude exceeds 2000 meters in actual use, it will affect the heat dissipation and insulation performance of the sensor. It will reduce the insulation characteristics, although the insulation can also be improved by external methods, but it is difficult to achieve and will increase the cost, in the actual selection and use is to refer to the rules of the 1EC60664-1 specification to reduce the derating use, please refer to IE°C60664-1 Section 5.1.4, Table VIII.2 for derating coefficients. The problem of heat dissipation can be solved relatively simply by means of forced air cooling.
3. Device orientation
Because the sensor is a non-contact measurement, most of the sensors detect the magnetic field around the live conductor, so there should not be a strong magnetic field near the sensor, and the equipment that simply generates the magnetic field. It includes transformers, reactors, and conductors that flow high currents, etc. Especially in three-phase testing, adjacent sensors should not be installed too closely. In the case of space promise, the distance is as large as possible.
Sometimes it will be constrained by the cabinet and its internal layout, and it is difficult to leave a satisfying space, in this case, it is advocated that the sensor dislocation device, especially the sensor of the H8LL principle, should be as far as possible to let the orientation principle of the HALL equipment magnetic field source.
