5- and 15-kV
Megohmmeters
5- and 15-kV
Megohmmeters
■ Continuously variable test voltage
■ Rugged field construction
■ Circuit-breaker protection
DESCRIPTION
The 5- and 15-kV Megohm-meters are high-voltage, line-
operated instruments. They provide a continuously
variable test voltage for highly sensitive insulation-
resistance 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 step-
voltage testing. Two models are available:
The 5-kV Megohmmeter measures up to 100,000 M
Ω
;
provides output from 250 volts to 5 kV, with direct reading
up to 50,000 M
Ω
at 2.5 kV.
The 15-kV Megohmmeter provides direct reading
measurements up to 100,000 M
Ω
at 5 kV and up to
200,000 M
Ω
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.
FEATURES AND BENEFITS
■ Provides 2% kV and M
Ω
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
■ Rugged field construction
