When there is a danger of being exposed to an electric arc, personnel are advised to wear arc approved protective clothing. IEC 61482-2 is the overall standard that covers protective clothing against the thermal arc hazards of an electric arc. The IEC 61482-2 standard also covers various aspects of the garment design. This is a requirement for selling garments for arc flash protection within the EU. Garments complying with all of these requirements outlined under IEC 61482-2 should be marked with the IEC 61482-2 symbol as well as the level of protection it meets.

From minor control trips right down to compressor and transformer failures, harmonics can have an impact on every type of HVAC equipment. Surprisingly, harmonics is something that quite often can be overlooked. Harmonic currents and the electrical distribution system Harmonic currents flow in a circuit at multiples of the fundamental 60 hertz (Hz) frequency. For example, current flowing in a circuit at 180 Hz is the third harmonic (60 Hz multiplied by 3). These currents are not indicated on multimeters and therefore are usually not detected until unusual control and equipment problems start to happen. Comparing these current readings from … Continue reading →
