3 Easy Steps to stop Bearing Current Failures with Drives

How to deal with persistent bearing currents On rare occasions, operators in the process industry may note that their low voltage motors experience a current flowing through the motor bearings, especially when they are used with a variable speed drive (VSD). Left unchecked, these bearing currents will inevitably result in premature failure. Two new approaches can eliminate …

All your drive needs taken care of, for less than the price of a cup of coffee a day.

There are over 10,000,000 motors installed in the UK with over 50% of them controlled by variable speed drives, that percentage increase to a staggering 92% on critical drive applications. Today’s modern drives have on average over 1000 different parameters that can bet set by the user to exactly match your process. Modern drives have …

Eight practical applications of testing ground system using clamp-on tester.

Understanding the ground system First of all, it is extremely important that the operator/engineer understand the ground system that is being tested. The clamp-on measurement works well in many situations, but it has limitations and is not applicable in some configurations. Clamp-on ground testing is a relatively new method of determining the quality of a …

How to know if you set the correct current on a motor thermal overload relay

Start with full-load current… The full-load current at a given voltage indicated on the nameplate is normative for setting the overload relay. Because of the variable voltages around the world, motors for pumps are made to be used at both 50 Hz and 60 Hz in a wide voltage range. Therefore, a current range is …

Why you must use Variable Speed Drives in pumping applications!

Variable speed drives in pumping applications Pumping applications represent a significant opportunity for applying variable speed drives (VSDs) in new, as well as retrofit installations. The majority of pumping applications need to be controlled. It is unlikely that a pump will run continuously at a maximum speed.     Many analyses show that energy consumption is …

The essentials of electrical distribution systems every engineer should know.

Transferring AC/DC electrical power Electrical distribution systems are an essential part of the electrical power system. In order to transfer electrical power from an alternating current (AC) or a direct current (DC) source to the place where it will be used, some type of distribution network must be utilized. The method used to distribute power …
