∙ 13y agoAn earth leakage protection device comprises a core balance current sensing transformer 1 having a secondary winding 2 in which a fault signal is generated in response to leakage from AC supply lines forming primary windings of the transformer 1, an operational amplifier OA1 for amplifying the fault signal, a precision rectifier circuit 8 comprising a pair of operational amplifiers OA2 and OA3 for performing full wave rectification of the amplified fault signal, a delay circuit 9 in the form of a two stage RC network which delays the rectified signal according to an IDMT characteristic, and a trigger circuit 10 in which the delayed signal is compared with a preset reference signal by an operational amplifier OA4 to provide a control signal which actuates a sagety device in the AC supply lines via a relay 11 when the reference signal is exceeded. Within its operating range the device actuates the safety device much more slowly for lower leakage currents than for higher currents, and since it is operative on both halves of the AC leakage current signal the device provides reliable protection against the possibility of dangerous electric shocks while avoiding spurious tripping.

What is the working procedure of EARTH LEAKAGE CIRCUIT BRACKER?
we call them ground fault breakers 10 milliamps thru you instead of the normal current path can kill you if you have a neon test lamp connect it to one of the hot leads and earth the other. if it lights the earth leak detector is faulty. if it opens the breaker its good most here in the usa have a test button
Where does earthing current go?
it takes the lowest resistance path back to the current source Answer: Earth leakage current flows down to earth through the consumer earth continuity conductor.
What is mean by 4 pole ELMCB?
Earth leakage miniature circuit breaker (mcb+ecb=rcbo) rcbo is called elcmb
What happen if you connect earth wire in place of neutral wire?
If there's no earth leakage protection unit in your main Distribution Board then the device will operate normally since the neutral and earth conductors are one on the supply side. But if there's Earth Leakage then because of the imbalance in the currents flowing through the Earth Leakage it will trap. What is called 'earth wire' in Europe is called 'ground' in the US and is often bare. Using a bare conductor as a neutral exposes you to potential shock. If the bare wire is properly connected at the panel, all is fine. But if you touch this bare neutral and provide a better grounding connection than the panel provides, you become part of the circuit to whatever device that circuit supplies. What is often missed in this scenario is that with the neutral being after the load, the load limits the current and your shock WILL NOT TRIP THE BREAKER.
Can a ground leakage damage electrical appliances?
A ground leakage can damage electrical appliances. When there is a current leakage, it causes the appliance to draw more current through thecircuit, hence produces excess heat. This can damage the appliances.
How do you solve earth leakage?
The best way to stop earth leakage is to make sure that the are no active circuits going to ground. This will help keep the circuit running right.
Can loose neutral wire effect the operation of Earth Leakage Circuit Breaker?
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.

What is the difference between Earth Fault Relay and Earth Leakage Relay?
Earth leakage relays are instantaneous tripping relays where as earth fault relays have the option of time and ampere setting i.e. for a setted ampere the circuit breaker will be tripped off after the setted time (in second).
How does cable sizing calculation gets affected by earth leakage protection?
Ground / earth protection will not impact cable sizing.
What is the value of surface resistance for conductive flooring?
It's the Earth leakage resistance (Ohm)
How do you know you have got an earth leakage?
there will be current that isn't carried by the current carrying conductors
What is the testing procedure for an earth leakage circuit breaker?
You can test this breaker by clamping it onto the earth cable. This will provide you with the measurements that you need.
