Current Transformers Accessories for
Power Quality
Used with the PA-9Plus and other data recorders
Available in a flexible or clamp-on option
A number of lengths and sizes for all power
measurement needs
Special rain tight CT allows for functionality in
outside environments
Easy to use and install
Megger offers a comprehensive line of both
flexible and clamp-on current transformers that are used with power quality
analyzers and recording volt-ammeters. These accessories are specifically geared
for use with the entire PA-9 Series along with the SLM-8 Recording Volt-Ammeter
and the older PA7, RVA4 and RA recorders. The CT, also known as a current
probe (CP) or current clamp, is self powered and does not require the use of a
battery when used with Megger PA-9 or PA-9Plus instruments. Megger also markets
a battery-operated CT for customers who require one with their power quality
product or older Megger unit.
BATTERY GROUND-FAULT
LOCATOR Battery Test Equipment
Ground faults in ungrounded dc battery systems
easily located
Operates in high electrical noise environment
Simplifies fault tracing by identifying fault
characteristic (resistive and capacitive) magnitudes
This instrument was developed to detect, track and
locate ground faults on battery systems – without resorting to sectionalizing!
Model BGL tracks and locates ground faults on live or dead battery systems. To
save hours of unnecessary troubleshooting, the BGL readily differentiates
between the resistive fault currents and capacitive charging currents. This
feature allows the instrument to detect and track leakage paths, even in the
presence of surge-suppression capacitors.
Megger MFT1553 On-site Multifunction tester with Bluetooth communications to mobile devices and 16th and 17th Edition certificate completion
Complete certificates on-site as you go
Store the certificate and complete it on your
mobile device, smart-phone, PDA or laptop
Send results from your MFT1553 multifunction
tester direct to the correct location on the certificate
Reduce error
Increase productivity
Saves you hours of form filling
The Megger MFT1553 On-site is an amazing new
pairing of a superb test instrument and a software package that allows you to do
your testing and complete your certificate as you go there on-site.
The certification software, PowerSuite On-site, can
be run on mobile devices such as your smart mobile phones, PDA or laptop and
once paired with the tester, and the circuit number entered, the meter will send
the test result to the correct field in the certificate.
Your device will acknowledge receipt of the result
and allow you to check that it has dropped in to the right field.
It is truly remarkable and more importantly it
saves errors in reading the test results, writing them down, in transcribing to
the certificates. Not only does prevent error it saves huge amounts of
time.
