Dielectric test sets measure leakage current while applying a dc voltage at or above the insulation systems operating level. This measurement aids in determining the insulation systems ability to withstand over voltages such as lightning strikes and switching surges. Reads Leakage Current from 1 to 5,000 Microamps Test Ranges: 0-2.5/0-5 kV DC, Continuously Variable 5 mA Continuous Output Current 10 x 13.5 x 9.5 HWD/20.5 lbs. Compact and portable Air insulated, uses no oil ±2% accuracy Leakage current measurement as low as 0.1 mA Continuously variable test voltage with zero-start safety interlock Fast charging of high-capacitance samples Current guard circuit for highly accurate measurements Strip chart recorder for hard copies (optionally available) Input and output line circuit breaker Output current overload relay Zero-start interlock for high-voltage output Switch control and indicating lights for high-voltage ON/OFF on the 15-kV model Full circuit breaker protection 15 kV model > Each Unit Includes Power Cord High Voltage Cable (40586) Ground Cable (4702) Instructions
