Megger 15 kV DC Dielectric Test Set; 7.5 & 15 kV; 5 mA
Dielectric test sets measure leakage current while applying a dc voltage at or above the insulation system s operating level. This measurement aids in determining the insulation system s ability to withstand over voltages such as lightning strikes and switching surges.
Features:
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)
Safety and Reliability
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
