American vanguard OLTC transformer tester LTCA-10 Load Tap Changer Analyzer

American vanguard OLTC transformer tester LTCA-10 Load Tap Changer Analyzer The LTCA-10 Analyzer is a second generation load tap changer analyzer. The LTCA-10 accurately measures winding resistance of highly inductive power transformers. Triple resistance-reading channels allow the measurement of three winding resistances simultaneously. Four-wire (Kelvin) connections provide high accuracy and require no lead compensation. A special feature of this device is its ability to measure and graph the resistance trace of a transformer LTC during operation. Using a 60Vdc power supply, the LTCA-10 is capable of outputting 10 amperes. Auto discharge circuit for operator safety 3 resistance reading channels including one dynamic channel Digital resistance reading from 1 micro-ohm to 500 ohms Calculate equivalent resistance value at reference temperature Stores 50 static records and 20 dynamic records Built-in 4.5-inch thermal printer Weighs less than 44 lbs.
