Who Else Wants to Reduce Electrical System Downtime in Hospitals?
NHP, Terasaki's partner in Australia, has recently released a case study featuring Terasaki AR ACBs. You can view the video below:
The power distribution infrastructure at Monash Medical Centre in Melbourne was end of life and needed to be replaced. NHP met with the hospital to understand their requirements and recommended a SMART closed transition switch solution made possible by the Terasaki ACB, which guarantees a seamless transition from mains power to generator. This has reduced the need for months of planning for when the hospital undertakes mandatory quarterly testing of its generators, all the while keeping patient safety at the forefront.
Please visit the project references section on our website for more examples of case studies/projects where our TemPower 2 ACBs have been applied.
From the design office to the factory floor, quality is part of the ethos by which we all operate at Terasaki.
Quality overarches design for manufacture, design for maintainability, manufacture for reliability and results in long and trouble-free product life for our customers.
It’s in our corporate DNA.
Take, for example, our TemPower 2 ACB range.
Elegant design includes unique features such as: -
Our "Double Break" contact system ensures extremely fast interruption of short circuit currents. Energy is dissipated at two points on each pole within the breaker resulting in minimised erosion of the contacts and increasing the reliability of the breaker.
Our proprietary active sensor system continually monitors temperature of the conductors at the contacts and can signal an overheating alarm before irreversible damage occurs.
Uniquely, TemPower 2 ACBs have their isolating clusters and racking mechanism on the ACB body rather than the chassis. Having all the maintenance touch points on the body side allows shorter time to repair (MTTR) and minimal downtime.
But don’t just take our word for it, download the pdf to reveal more detail of these innovative features. Take a look at the testimonials of our customers in critical applications, harsh environments and remote installations.
Direct operation of switchgear is one of the most frequent exercises that exposes an operator to risk.
Remote switching permits operation of the circuit breaker at a safe distance.
Circuit breakers can be opened and closed from a remote location, removing the operator from the area of risk, and allowing a reduction in the level of personal protective equipment (PPE) required for the operation.
Using the Terasaki ACB remote controller provides a safer operating environment for personnel through the proven method of adding distance between the operator and the risk.
You can significantly reduce the cost of equipment for large solar farms by spending less on cable. Developers want to achieve this by transmitting power at higher voltages. Lower currents will be carried to the “collector” switchgear by cable with smaller cross-sectional area and lower cost. The trend is to transmit at 800V AC.
Terasaki support this opportunity for developers to reduce cost. We’ve type-tested a new range of circuit breakers for 800V AC. The VE400-NE MCCB and AR3H-V8 ACB handle fault currents up to 30kA at 800V AC. Current ratings from 100A to 3200A.
Following the recent successful roadshow we have taken on board customer feedback and have developed the GroupStak to include the following features:
Form 3b solution.
The GroupStak switchboard is now developed to include a form 3b option.
This offers a higher stacking density at lower price than the standard form 4b version. Maximum number of feeders of different types are listed below:
56 - single pole MCCBs, max 125A
21 - 3 pole MCCBs, max 160A
17 - 3 pole MCCBs, max 250A
12 - 3 pole MCCBs, max 400/630A
GroupStak is now design verified with outgoing MCCBs with electronic protection.
TemBreak 2 MCCBs from 250A frame to 630A frame are available with electronic protection units. Current ratings, In, of 40A, 125A, 160A, 250A, 400A, 630A are available. These offer flexibility as their characteristics can be set between 0.4 and 0.1 times In.
Every TemBreak 2 electronic protection unit includes overload protection (L), delayed short-circuit protection (S) and instantenious protecion (I) as standard.
Metering and CTs
Metering and CTs
GroupStak has now been developed to accept Rayleigh’s Easywire plug and play meters and CT's.
The steel work is pre-drilled for ease of mounting with pre-cut clear cover plates and door cuts-outs on request.
Many specifications request provision for future additions (spare ways). GroupStak can have spare ways included without MCCBs fitted. They have pre-coppered to the main bus bar making it a quick and easy job to add future MCCB outgoing devices.
How to Select and Set Circuit Breakers for Generators
Generators differ from other electrical power sources in their ability to withstand electrical overloads and fault currents. These differences should be respected when selecting and setting circuit breakers which protect generators.
Terasaki have prepared a designed guide that explains the parameters of generators and circuit breakers which should be considered when selecting and setting circuit breakers which protect generators.
