The 2V16x Series relays are designed for the control of motor driven on-load power transformer tap changers. The 2V165 Series relays are designed to monitor & control the tap changers of up to four (4) transformers connected on a common bus & operating in the master slave control configuration. Master follower parallel control schemes traditionally use auxiliary switches on the tap changers to determine out of step errors. While this is a reliable & proven technique there are two significant drawbacks:
1. Wiring complexity between the tap changer auxiliary switches
2. Requirement for matched tap changers
The first issue is overcome by replacing each tap changer auxiliary switch with a TPI transducer (2V200), which sends a frequency signal proportional to the tap position. This requires only two wires for each tap changer & is simply wired back to the 2V165. The second issue is overcome with a user specified tap position logic table in the 2V165 to allow non-matched tap changers to operate together. The tap position of each transformer is monitored as well as the raise / lower commands initiated by the selected master voltage regulating relay. The 2V165 responds by sending the appropriate raise / lower commands to each tap changer in accordance with the tap position logic table.

What has not changed from the 2V165
This page is designed to provide the latest technical information and software downloads for the 2V165 Relay.
The compatibility of a specific software application version with a hardware Type Number can be verified from the Compatibility.pdf document.
Use the “Save File As” command to download the required ZIP file which contains four items:
The last 4 digits of each .zip file is the software version number which can be checked against the issue level of a relay’s software by accessing the DIAGNOSTICS page from the front panel. This is done by pressing the DATA and SET buttons simultaneously, moving the curser over “VERSION” and pushing SELECT. To load a .umx or .ump file you need to connect to the relays RS232 port using a PC with the uMATRIXwin software.
