Types of Voltmeter
1. analog voltmeter, analog voltmeter are rotating device rotating frame Baazafh a resistance in series with the coil (frame) is used as a voltmeter. 2. The digital voltmeter: digital measurement devices due to the lack of moving parts, very high lifetime (if using them correctly) are entitled to physical factors such as vibration, humidity, air cleanliness and ... not case sensitive .
Read MoreTypes of air-termination system
Air-termination systems can be either isolated or non-isolated systems; the two types can be used in combination. Non-isolated systems are fitted directly to the object that is to be protected and the down-conductors are routed along the surface of the installation. Isolated systems prevent direct strikes into the object/installation that is to be protected. This can be achieved with air-termination rods and masts, but also by fixing the components with insulating GRP (fibre-glass-reinforced plastic) holders to the building/installation to be protected

Read MoreUse of natural components
Metallic installations can be used as natural components of a down-conductor system, provided that: • Electrical continuity is permanent, • Their dimensions correspond at least to the values for standardised conductors (Table 2.6). • Pipelines with combustible or explosive contents are not permitted, if the seals in flange couplings are not connected so that they are electrically conductive.
Read MoreWhat is Switch-mode Power Supplies (SMPS)
Switch-mode Power Supplies, are electronic power equipment, which include switching controller, for converting electric power to another voltage level. Switch-mode Power Supplies (SMPS) like other power supplies can be connected to one bigger source and transform energy to loads by different currents and voltages. Unlike linear power supplies, power transistors of switch-mode Power Supplies turn on and off, constantly, and as a result, these equipment have minimum loss power.
