5- and 15-kV Megohmmeters 5- and 15-kV Megohmmeters DESCRIPTION The 5- and 15-kV Megohm-meters are high-voltage, lineoperated instruments. They provide a continuously variable test voltage for highly sensitive insulationresistance measurements of all types of electrical equipment and power cable. The instruments are designed to withstand harsh field conditions, and feature tough, impact-resistance casing, removable lids and adjustable carrying straps. For complete portability, there is ample room in each case to store cables and the instruction manual. APPLICATIONS The units are suitable for dielectric absorption and stepvoltage testing. Two models are available: Continuously variable test voltage Rugged field construction Circuit-breaker protection FEATURES AND BENEFITS Provides 2% kV and M accuracy Guard terminal to eliminate surface leakage current from the measurement Zero-start, high-voltage interlock Shielded, high-voltage output cable permanently connected to the instrument Circuit-breaker protection Redundant grounding connections Easy-to-follow, color-coded meter scales Analog metering for monitoring of variable measurements The 5-kV Megohmmeter measures up to 100,000 M; provides output from 250 volts to 5 kV, with direct reading up to 50,000 M at 2.5 kV. The 15-kV Megohmmeter provides direct reading measurements up to 100,000 M at 5 kV and up to 200,000 M at 10 kV, with a multiplying factor for all other voltages up to 15 kV. The 15-kV model also features an internal voltage stabilizer that may be activated for improved measurement under extreme field conditions. Separate on/off controls are provided for power and high voltage, and a red light indicates when high voltage is on. Rugged field construction 5- and 1-kV Megohmmeters SPECIFICATIONS Cat.
