I am looking for someone to design Motor protection relays for us and other type switch gear protection. The motor protection relay I am looking for must include True RMS Measurement up to 2500 VAC phase to phase and true RMS current up to 6500A per phase. Sensitive earth leakage protection from 30mA to 6A. it must also have a live line indicator on all three phases, and it also must have an earth lock out function to detect earth fault before the motor has started, it also must have an automatic earth leakage self test which can be logged. I would like the following featrures

* Three True RMS Channels
* Two True RMS current channels
* Sensitive Earth leakage protection
* Earth Fault lockout protection
* Three Binary NO/NC inputs
* Four Voltage free contacts
* USB Communication
* Live Line Indicator
* Real Time Clock
* Under/over voltage protection
* Under Current protection with definite time trip
* Over Current protection IDMT or define time trip
* Start up protection and thermal stress calculation
* Data logging of all events including start/stop and power up

I would also require the full schematic. PC Board layout and Gerber files

Expert Guarantee Required:

     It is crucial to the buyer that this entire bid request be completed (100%) by the deadline of 30 days. They only want expert workers who will commit themselves to this deadline to bid. If you are not an expert or unable to commit completely to the deadline, then DO NOT BID on this bid request.

     If you are an expert and can commit, the buyer would like you to demonstrate this by making an Expert Guarantee of at least 100% of your bid. (This would not need to be made now...but only if and when you are are selected as the winning bidder). If you complete the job (100% by the deadline), then your deposit would be refunded to you. If you do not, then you would forfeit the deposit and it would go to cover the buyer's cancellation charge and the remainder donated to a non-profit charity.

     Please note that depending on how you choose to make the deposit, there may be a small, non-refundable processing fee. This fee can be reduced or eliminated by choosing a less expensive method of payment. Or, you may wish to ask the buyer to cover the cost of the fee for you. You can do this in a number of ways such as: increasing the price of your bid, asking the buyer to post a 2nd bid request to cover it (contingent on completion of the bid request), or by getting the buyer to promise to pay the fee to you as a bonus (upon completion of the bid request). If you choose the bonus route, just remember that due to credit card/PayPal rules, Rent A Coder CANNOT force a buyer to pay a bonus involuntarily...even when promised on-site. So don't choose this option, unless you trust the buyer, or are willing to take a small risk.

     This is just a very brief overview of how the Expert Guarantee works and there are many more details that you need to understand fully before you bid on this bid request. DO NOT BID on this bid request until you've read and fully understand everything about the Expert Guarantee (including reading the contract and the FAQs).
