MAG-219 Version 3 – NOV/18
3 PRODUCT OVERVIEW
APPROVED FOR EXTERNAL DISTRIBUTION – PROPERTY OF AMPCONTROL PTY LTD – NOT TO BE REPRODUCED IN PART
Description
Ampcontrol’s ELV-PRO is a high performance, microprocessor based, wide bandwidth earth leakage protection relay that is capable of measuring and analysing power and switching frequency currents flowing in IT power systems. The ELV-PRO uses patented technology (US20130258537) to characterise earth leakage currents giving superior fault discrimination.
The ELV-PRO relay is designed for use in systems that may exhibit circulating earth currents and complex earth leakage currents typically associated with variable speed drives in mining environments.
Key Features
The ELV-PRO has the following key features:
Compliance to AS/NZS 4871 and AS/NZS 2081
Patented earth leakage analysis method*
Fail safe operation
Wide range Earth Leakage Current Measurement (20 Hz to 8 kHz)
Wideband, Narrowband and Weighted Frequency Response Modes
Adjustable trip level and trip times
On board memory logs last 1000 data logs and 50 events
CIP over EtherNet/IP for control and Monitoring
Modbus TCP
Continuous Toroid Connection Monitoring
DIN rail mounted
*International patent application number PCT/AU2011/000705
Application
The ELV-PRO is intended for use at transformer NER connection points as a BUEL Protection relay. The relay is not limited to be used in this configuration only, and can be utilised on any individual outlet if desired. This would allow greater earth leakage current data to be captured relating to a specific outlet, rather than the entire system connected to the transformers secondary that the NER is protecting.
The ELV-PRO provides data logging to assist in fault finding. On each event trigger, the relay stores system data two seconds before and two seconds after the event including system time, earth leakage current, phase current and zero crossing of the phase current.
Ethernet connection to the ELV-PRO relay provides the ability to monitor the device parameters and real time measured current from an internet browser. All data logs stored on the unit can also be viewed.

4 INSTALLATION
General Warnings
These instructions have been designed to assist users of the ELV-PRO with installation.
Before the ELV-PRO can be installed, there are a number of things that need to be considered and understood to prevent incorrect or unsafe operation of the relay or the system into which it is installed.
Along with relevant competence, and an understanding of the target application, the following points should be considered:
4.1.1 Ensure that the information provided in this user manual is fully understood.
It is extremely important that the limitations and functionality of the relay are understood to prevent incorrect installation or use, creating a potentially dangerous risk. If in doubt as to the nature of the limitations or their implication, consult a competent authority such as a supervisor or Ampcontrol technical representative.
4.1.2 Ensure that the application into which the relay is being installed has been properly defined, designed and approved.
Any system intended to mitigate the risk of injury needs to be properly designed and implemented. Such a system must be the result of structured risk analysis with the outcomes used to define the system requirements. These requirements, in turn, will guide the choice of instrumentation, logic solvers and actuators needed to implement the system. Understanding the needs of the system will ensure proper selection of equipment.
4.1.3 Ensure that the relay will properly perform the required functions within the system design.
It is important to understand how the relay is intended to interact with other equipment within a system. For safe and reliable use, it is crucial that neither the logical operation nor its signalling be compromised by incompatibilities with connected equipment.
4.1.4 Modifications of any form to the relay are prohibited.
If modifications of any form are made to the relay, the equipment may no longer be fit for use. If any modifications or damage to the relay is evident, do not use the equipment and contact Ampcontrol for advice.
Mandatory Installation Practices
The following information must be adhered to when installing the ELV-PRO. Failure to adhere to this information may give rise to unsafe operation.
Using the relay in a manner that exceeds its electrical or functional specifications, or in a way that is contrary to its operating restrictions, may create risks to personnel and/or equipment resulting in injury or death.
The ELV-PRO must be supplied by a regulated voltage within the specified range.
The installation of the ELV-PRO must be carried out by suitably trained and qualified personnel.
Identification labels fixed to the ELV-PRO must not be damaged, removed or covered.
The installation is to be in accordance with the relevant installation Standards/Codes of Practice.
Modifications must not be made to any part of the ELV-PRO. Modifications to its construction will render the unit non-compliant.
Complete and accurate records of the installation must be retained for warranty purposes.

4.4.2 Trip Reset and Digital Inputs (Plug 2 & Plug 4)
The trip reset and digital inputs are split across two plugs; Plug 2 and Plug 4 (see Figure 4-5). Plug 2 (right) is a dedicated digital input and Trip Reset 24V supply. All terminals of plug 2 are internally connected. Plug 4 (left) is a dedicated input plug; terminals P4_1 - P4_5 are assignable digital inputs, with terminal P4_6 the Reset input. The Trip Reset Input allows the ELV-PRO to be reset remotely.

4.4.3 Earth Leakage CT, CT Test, Zero Crossing Input Connections (Plug 6)
The Earth Leakage protection is achieved through the use of a core balance CT. The connections to the CT are terminals P6_1 & P6_2. Terminal P6_3 is the screen termination point for the cable connecting the EL CT to the relay. For further details see Section 4.4.9.
NOTE |
The loop impedance of the cables used to connect the phase CT to |
|
|
|
the ELV-PRO relay must be less than 0.1Ω. It is recommended that |
|
this is wired as a twisted pair shielded cable. |
|
|
APPROVED FOR EXTERNAL DISTRIBUTION – PROPERTY OF AMPCONTROL PTY LTD – NOT TO BE REPRODUCED IN PART
To ensure the CT is connected and the signal the relay monitors is correct, a CT test output is provided on terminals P6_5 & P6_6. A missing CT Test signal through the CT will cause the ELV-PRO relay to trip. The test signal is applied every two seconds, and may be seen on the live screens and data logs.
Terminal P6_4 of Plug 6 is a general earth connection.
The Zero Crossing input, terminals P6_7 & P6_8, is provided for logging purposes.

NOTE |
The protection system constantly injects a CT test signal into the CT |
|
|
|
every two seconds. As such, the earth leakage graph will record a small |
|
|
|
non-zero value, even when the outlet is open (Not connected to the |
|
|
|
load). This confirms that the Earth Leakage system is operational. |
