ATRT-03 S2, ATRT-03A S2, AND ATRT-03B S2 USER’S MANUAL 2.0 PRE-TEST SETUP 2.1 Operating Voltages REV 2 All three ATRT-03 S2 models can be powered by ac line voltage of 100-240 Vac, 50/60 Hz. For greater flexibility, the ATRT-03A S2 features an internal rechargeable lead acid battery and can also be powered by a 12 Vdc external source. The ATRT-03 S2 has built-in ground fault isolation detection and will only operate with voltages that are ground-fault isolated. 2.
REV 2 2.5 ATRT-03 S2, ATRT-03A S2, AND ATRT-03B S2 USER’S MANUAL Replacing the Load Tap Changer Controller Fuses The ATRT-03 S2 features a built-in Load Tap Changer (LTC) controller that can raise or lower the LTC tap position from the front panel. The LTC controller circuit uses two 250 Vac/2A, NO, relay contacts to simulate the LTC Raise/Lower switches. Each relay contact is protected by a 1A/250 Vac fuse (5 X 20mm, fast acting). The fuse should be replaced with a Littlefuse P/N 217001 or equivalent.
ATRT-03 S2, ATRT-03A S2, AND ATRT-03B S2 USER’S MANUAL REV 2 b. The LTC control board is located under the left side of the front panel as shown in the figure below. Flip the unit over to easily access the LTC control board fuses. c. Replace any fuses as necessary with Littlefuse P/N 217001 or equivalent (250 Vac/1A, 5 X 20mm fast-acting type). d. Re-secure the unit in its casing with the screws that were removed in step a.
REV 2 3.0 ATRT-03 S2, ATRT-03A S2, AND ATRT-03B S2 USER’S MANUAL OPERATING PROCEDURES The ATRT-03 S2 should always be grounded with the provided ground cable before connecting H and X cables. The transformer bushings should also be grounded before connecting test leads to the transformer. This will prevent inducing any voltages into the ATRT-03 S2. All transformer bus connections must be removed, and the transformer must be isolated before performing any tests.

REV 2 3.2 ATRT-03 S2, ATRT-03A S2, AND ATRT-03B S2 USER’S MANUAL Setting the Test Voltage The ATRT-03 S2 offers three test voltages, 8 Vac, 40 Vac, and 100 Vac. The unit always defaults to 40 Vac at power-on. The 8 Vac test voltage is for testing transformers which require low test voltages, such as metering Current Transformers (CT’s). For metering CT’s, higher voltages may drive the CT’s into saturation, thus giving invalid results. The 40 Vac test voltage is recommended for testing power transformers.
