Motor Control and Protection Requirements on Modern Industry

The electric motor has become one of the most notorious inventions of man along its technological development. Indeed, electric motors are the spine of the modern industry. Despite their ruggedness and simplicity in construction, motor failure rate per year is significant. In some industries, particularly mining and quarrying, pulp and paper, cement, among others, motor failure rate has been even bigger than in other segments. Because continuity of service is imperative in these industrial fields, the downtime for repair or replacement, removal and installation is very costly. Therefore, proper motor protection becomes important to keep processes functioning ensuring productivity targets, personnel safety and to prevent unplanned outages.

Usual motor feeder circuits comprise a motor starter and a suitable short circuit protection device. The motor starter is normally defined as a combination of switching means necessary to start and stop the motor in combination with suitable overload protection.

The main purpose of a motor protection system is to prevent excessive temperature increases in the windings due to over current conditions. Coordinated motor protection should also enable continuity of service. This continuity of service can be achieved by matching the characteristics of the short circuit protection device with the motor starter and cables to ensure that faults do not rise above levels that may endanger personnel or damage equipment.

What is the difference between Type 1 Co-Ordination and Type 2 Co-Ordination Switchgear?

The International Electrotechnical Commission (IEC), one of the world’s leading organisations that publishes standards for all electrical and electronic fields, sets in the IEC 60947-4-1 requirements for switching and protection components for motor feeders. This is done to ensure safety to the user and ensure that components that meet the standard will provide the expected performance.

Both Type 1 and Type 2 Co-Ordination switchgear will safely clear any short circuit that occurs. In the case of a short circuit condition, with both Type 1 and Type 2 Co-Ordination switchgear there is no danger posed to personnel or to the installation itself. The primary difference is that Type 1 Co-Ordination switchgear is considered the basic solution, while Type 2 Co-Ordination switchgear is considered the high performance solution.

Should a short circuit condition occur when using Type 1 Co-Ordination switchgear, this equipment will no longer be functional and will need to be replaced. Furthermore, qualified maintenance personnel are required to replace the motor starter (contactor and/or overload relay).

Where a short circuit condition occurs when using Type 2 Co-Ordination switchgear, this equipment will still be suitable for further use. The risk of a small contact welding is recognized, in which case the manufacturer shall indicate the measures to be taken as regards the maintenance of the equipment.Basically Type 2 Co-Ordination switchgear will ensure safety and continuity of service, irrespective of short circuit conditions.

It is also important to bear in mind that not all low voltage switchgear ranges offer both Type 1 Co-Ordination and Type 2 Co-Ordination. This is because the equipment and equipment combinations need to be extensively tested to ensure that these meet the required IEC standard.

www.weg.net


WEG Type 2 Co-Ordination TestsUsers look for guidance and recommendations about which specific SCPD should be used along with a given motor starter according to the voltage and short circuit levels of their application.

Emphasis should be given that the knowledge of a Type 2 Co-Ordination solution is only achieved by carrying out tests, which require knowledge about the application, installation codes, product standards and its characteristics, and need abundant product samples and availability of a high-capacity short circuit test facility.Indeed, in order to provide this information, exhaustive and successful short circuit tests, witnessed by an unbiased third party, have been carried out with different combinations of circuit breakers, overload relays and contactors, for levels of 50 kA at 550 V ac.

In fact, WEG tested and approved the following Type 2 configurations:� MCCB + Contactor + Overload Relay Class 10 with communication;� MCCB + Contactor + Thermal Overload Relay;� Motor protective circuit breaker (MPCB) with overload protection + contactor.

WEG sets an important differentiation thanks to its comprehensive portfolio of low voltage switch and controlgear that include all devices required on a Type 2 Co-Ordination motor feeder. This way, whenever a component (e.g. a contactor or overload relay) undergoes any design changes (which can affect the Co-Ordination with the SCPD), new round of Type 2 short circuit tests must be carried out. Such practice strengthens the confidence placed on the published ratings.

Internal arc test in a Motor Control Center carried at WEG facility. Currently the short circuit test infrastructure with higher capacity in a private facility in the South Hemisphere.

ACW Molded Case Circuit Breakers for Motor Branch Protection

WEG Products for Motor Switching and Protection with Type 2 Co-Ordination

ACWs are compact and robust molded case circuit breakers that can be provided with the “MTU” (magnetic trip only) release, specifically designed for motor starter protection. They are available in three different frames with rated currents from 20 to 630 A. There are a wide range of accessories available, including panel door rotary operating handles, motor operators, shunt and overvoltage releases and auxiliary contact blocks just to name a few.

The ACW design with double-breaking contacts produces a current limiting effect that interrupts faults within the first half-cycle reducing the current peak and energy of faults. That provides protection for the downstream motor starter and other equipment that could otherwise be damaged by the severe effects that short circuits usually produce.

Additionally, thanks to their high short circuit breaking capacity, ACWs perfectly match with WEG contactors and overload relays providing complete load feeders Type 2 Co-Ordinated for levels of Iq = 50 kA at up to 550 V ac.

The MPW40 motor protective circuit breaker (MPCB) is a thermal-magnetic circuit breaker that combines in a single compact unit, the short circuit and isolation functionality of a MCCB with the motor overcurrent protection of a traditional tripping class-10 overload relay. When used along with a suitable contactor (the switching component), these two components comprise a complete and cost effective solution for motor starting and protection. The circuit breaker is definitely the component most affected by short circuit currents. Thus, maybe because of the compact size of the MPCBs, in the past there was a lack of confidence in these components, particularly when compared to bulky MCCBs.Indeed, MCCBs are really robust but years of research joined to technological development in many engineering fields led the MPCBs to become as reliable as any MCCB and now, MPCB’s compact size is considered a great advantage. An additional and important attribute of MPCBs with respect to effective short circuit protection is their low energy let-through values (the magnitude of the cut-off current and let-through energy in relation to the prospective short circuit current).In a few words, the MPW40 is a very limiting component and the stress of downstream contactors in the event of a short circuit is significantly reduced.

CWM and CWB Contactors

WEG CWB and CWM lines of contactors are suitable for the use on applications where Type 2 Co-Ordination is required. This accomplishment results from the fact that, in order to withstand high transient currents that short circuits usually produce, WEG contactors have undergone several optimizations in the past five years.

Even though the transient phenomenon only occurs in a semi-cycle of the current, a huge amount of thermal energy is dissipated. This way the most important and effective improvements have been the reduction of contact resistance and improvement on the insulation of the contactor frame. In order to do so, several components have been improved and it has been necessary to optimize the design so as to increase the magnetic forces and, in some cases, even increase contact spring forces. All optimizations have been carried out with the commitment to obtaining the desired improvements without reducing mechanical and electrical lifespan or increasing contactor’s coil consumption.

RW Thermal Bimetallic Overload Relays

RW thermal overload relays have been designed to be combined with CWM contactors to assemble motor starters. These reliable devices protect electric motors, controllers and branch circuit conductors against phase failures and overloads that may cause excessive heating. On thermal overload relays, the motor heating is simulated by passing motor current directly or indirectly through bimetal strips. The heat generated by joule effect (i²t) bends the bimetallic strips and, depending on the current set on the relay, a trip mechanism is activated. In order to comply with the Type 2 test requirements, the tripping of the overload relay shall be verified at a multiple of the current setting and shall conform to the published tripping characteristics, both before and after the short circuit test.
