RGDAT - Tester - Device introduction

The instrument DI2502, conforming to ENEL specification, is used for testing the device RGDAT (directional fault detection and voltage absence). The device allows you to check the RGDAT and accessories constitute the apparatus (current transformers, six-poles plug...). Using this device also allows you to check the main anomalies that are found in ordinary installation and maintenance of RGDAT, such as faults in six-poles plug, failure at final relay that do not change status and failures due to electronics.

The instrument was designed to allow use in conditions of full safety for the operator. Given the presence of a three-phase power, needed to test RGDAT, the instrument was built in double insulation and comply with safety standards conform to CEI EN 61010-1 Ed. II. The cover is plastic, resistant to heat, and all controls accessible by the user acting on a low-voltage devices that let you switch, through relays, the three-phase section.

Through a series of LEDs on the front panel and a signalling cable supplied, you can view the closure or not of the RGDAT relays.

The device is delivered  with some accessories: a coil of 650 A/turns to test protection 51, a coil of 200 A/turns to the protection 51N, two extensions 4m lenght with 4 mm plugs for link coil, power cord 4m length with 3 Phase + Ground + Neutral.

The tool is sold in a suitcase, hard and practice, which allows convenient transportation, both the instrument and all the accessories included

Signalling cable

It allows you to connect RGDAT signalling cable to the device DI2502, reporting the status of outputs. The connection with DSUB 9-pin on the front of the instrument can see, through LED lighting, closure or less of relay contact on RGDAT. The presence of two connectors, one male and one female, can perform the operation without interrupting the transmission of signals between the RGDAT and UP
