I. Product introduction
This product is an idea device for HV measuring; mostly apply in power
system, electronic equipment factory to test frequency AC high voltage and DC
high voltage.
This product is composed by HV divider and LV display meter. The two
parts are connected by the supporting cable.
II. Features
1. High precision
Uses high precision HV thin-film capacitor and HV glass glaze resistor,
input impedance is high, lower the measured current, small power
consumption, improves the accuracy and stability of the device.
For signal processing, adopts high performance OP to amplify the signal,
uses the newest dual integrating A/D sampling technique, four and half LCD
display, the maximum resolution up to 0.001kV, it is the replacement products
for HV electrostatic voltmeter.
2. Good anti-jamming performance.
Adopts special shield technique.
equipotential ball uses aluminum , effectively
improves the electric field distribution around the equipotential ball, prevents the point discharge,
improves the anti-jamming ability of the test results. LV display meter is full metal enclosed
instruction to shield,
Coaxial cable connect the HV divider and LV display meter,
reduce the effects to indicating value by high voltage, then realize high stability,
high linearity.
3. Safe and reliable.
This device is composed by HV divider and LV display meter, the HV
divider uses America Dupont packing material, special technique to embed,
with smaller structure, lighter weight, lower the internal partial discharge to the
least, more reliable, do not leak oil. Coaxial cable connect the HV divider and
LV display meter when working, the HV and LV parts are far away from each
