UBZ-301 Universal Protection Unit and Other Electromotor Protection Devices in the Market: Comparative Analysis

The majority of electromotor protection devices in the market (so called current protection) are practically equal in their functional capabilities which seem to be very primitive ones as compared with functional capabilities of an UBZ-301 Unit by NOVATEK-ELECTRO company production.

Protection against Faulty Conditions Caused by Neutral Phase Loss (Neutral Power Lead Breakage) in 3-Phase Distributor System of 220/380V

For the protection from neutral phase loss consequences we recommend to use microprocessor-based relay devices that are developed and produced by NOVATEK-ECLECTRO company. Use the RN-101 and RN-111 voltage relays in 1-Phase systems: the relays will trip for the minimum or the maximum voltage settings. Use the RNPP-301 and the RNPP-311 voltage monitors/relays in 3-Phase systems because the relays will trip for phase imbalance settings.

At the Interface of Two Problems: the Modern Approach to the Selection of Products for Development & Production

A manufacturer involved in any kind of production who is planning to expand a product assortment always has two possibilities. He can either manufacture the products at his own option and then to convince consumers that they are hard up for these products or study thoroughly consumer requirements and in close contact with the consumers to develop the products the customer needs. Obviously the second way is the most effective for the manufacturer and is corresponding to the modern world marketing tendencies.

Universal Protection For Induction Motors: Myth Or Reality?

Electric-to-mechanical energy conversion by dint of electric motors allows easily and economically to actuate diverse operating mechanisms such as conveyers, lifting-conveying machines, pumps, fans, compressors, metal-cutting machine tools, rolling mills, garment equipment and so on. Due to the construction simplicity, high reliability and the democratic price squirrel-cage induction motors (IMs) are considered to be universal electric motors.
