Nuclear Power 

It is important to maintain the process continuity of all the critical auxiliaries in the plant in the event of a contingency. With an experience of over 100’s of installations and decades of service, several of them in nuclear power plant installations in service since 2007, Aartech’s BTS 2000 Fast Bus Transfer Systems provides proven advanced numerical microprocessor based fast bus transfer solutions of ensuring safe and reliable bus transfer operations with the best international benchmarks.  Typically, a unit-to-station + station-to-unit three breaker configuration is employed to take advantage of the ability of the Unit Transformer (UT) and Startup Transformer (ST) to handle entire load of each other and are customized depending on the design, operational philosophy, economy and wish-list of the end user. While traditionally, these schemes have been applied to unit and station boards, they are increasingly being considered for other important switchboards and LT switchboards as well to establish a more robust and redundant operation in the plant.

Aartech is established and recognized in the field of bus transfer internationally, with several internationally published papers, approvals from major switchgear manufacturers, consultants, turnkey EPC contractors as established with performance certificates from our esteemed end user

A complete range of powerful yet economic, state-of-the-art microprocessor based protection solutions for a variety of standard feeder, transformer and motor protection as well as special customer defined schemes that require integration of features such as standard protection with special requirements such as islanding, bus transfer, load shedding, synchronization, SCADA interface and automation, developed through international collaboration are offered by Aartech’s Relay SSD.

Aartech’s Control & Relay Panels (CRP) SSD is organized to offer specialized custom built, integrated software engineered solutions involving aspects of protection, metering, communications and control for distributed automation, SCADA and remote telemetry based control and automation solutions.

Backup DG Sets are the last line of defense against a total AC failure. However, it is observed that they may not operate on demand due to problems in the batteries, maintenance issues etc. Similarly fire engines are considered a very critical fire safety protection in such installations.

Aartech’s KranKing Utlracapacitors can provide reliable engine starting solutions to ensure robust electrical support to the batteries at the time of engine cranking. A portable jump start system can also effectively provide for an arrangement to support the operations of multiple DG sets in a DG plant.

Fault levels of the MV switchboards may get compromised during re-configurations / capacity additions or operational considerations such as closing of tie breakers and grid interconnections. Even having fault levels within breaker handling capabilities, there is a considered need to reduce the fault energy, for eg. in the event of a transformer fault where severe consequential damages have been known to happen. Aartech’s fault current limiting solutions provided as a value added system integrator of M/s G&W USA offers internationally proven CLiP® Fault Current Limiter to customers all over Asia.

The control arrangements in a power plant are naturally elaborate and extensive. Usually, circuit faults in the control wiring are handled by use of HRC fuses or MCBs. Both require manual intervention for restoration.

Aartech’s load limiter system solutions in the form of Load Checker can act as an automatic resettable control fuse and thus provide for minimum downtime and repair/replacement costs and efforts.
