Guide to Medium and High Voltage Motors - A Quick Introduction

There can be different ideas about what qualifies as a low, medium or high voltage motor. “Some people consider anything above 1000 V as high voltage. The limits are clearly defined, however, in the IEC 60038 standard: low voltage is up to 1000 V, medium voltage is from 1000 V to 35 kV, and high voltage is over 35 kV.Get price

Difference Between High, Medium and Low Voltages | Generator

The lower current accompanying the high voltage transmission allows for the use of thinner lighter-weight cables. This reduces the cost in the tower and electrical line construction. High voltages range from 115,000 to 230,000 VAC and Extra-High voltages range from 345,000 to 765,000 VAC.Get price

The Basics of Personal Protective Grounding | ECM

PPGB EquipmentInstallation and Removal ProcedureMeps TechniquesAdditional RecommendationsSidebar: Hazards Associated with Temporary GroundingThis type of equipment is actually a system of connections, in that there are a number of points where the various components of the grounding cables must connect to the system to be grounded and to each other. It is vitally important to recognize that the grounding system is only as good as the weakest connection. In other words, having high-quality grounding cables but undersized grounding heads will render the system ineffective in protecting workers. There are a number of key concepts to remember when selecting PPGB equipment, including: Grounding heads — The grounding head is the only connection between the grounding system and the electrical circuit on which work is to be performed. Like grounding cables, the grounding heads must be rated to withstand the available fault current for the duration of the fault event. The data in the Tableidentifies the withstand ratings of one manufacturergrounding products. Grounding electrodes— The grounding electrodes are the other end of...Get price
