Grounding Current Meter Transformer Core Reactor Earth Current Tester 0mA-100A
Note:（Battery not included in the package）
Introduction:
Transformer Core Earth Current Tester, can online measure
the grounding current and leakage current of transformer core in electrical
power system（range: 0.00mA~100A）， The core is made of magnetic shielding
material with strong anti-interference ability, CT size: 80mm x 80mm, can
clamp and test Φ80mm cable and grounding wire. or 96mm×4mm flat steel grounding
wire. it`s no need to disconnect the tested circuit and can measure the line
current. The meter is equipped with a 3.5-inch color touch LCD screen, two
operating modes of touch and button, display the magnitude and waveform of the
measured current in real time. with alarm critical value setting , alarm
indication function, and automatic shutdown function. Normal operation of
the transformer core is a single grounding point , if there are two points or
more at the same time grounding, the core and the earth will form a current
loop, the maximum current up to dozens of amperes, which will cause the core
local overheating or even burned. This instrument can find latent faults of
transformer as soon as possible, which is one of the main tools to ensure
safe operation and normal maintenance of transformer. Mainly used for
leakage current testing of the core and clamps of transformer substation, power
station as the transformer, electric reactor and other electrical equipment.
The instrument consists of host, current clamp,
monitoring software and communication cable.The meter can store 200 groups of
data, which can be imported into the computer by USB interface. Monitoring
software can online real-time monitoring and historical query functions,
dynamic display, waveform indication, alarm value setting and alarm indication,
historical data reading, consulting, saving, printing and other functions.
