Turning the faintest signals
from power equipment into
predictable safety──
one thing we've repeated for 20 years.
From substations to GIS, from handheld inspection to 24/7 cloud monitoring — we build the complete signal chain that lets power engineers hear the symptoms before a fault arrives.

TEV
Transient Earth Voltage Sensor
High-sensitivity magnetic-mount sensor for TEV signals on HV enclosure surfaces.
Learn →
03
HFCT
High-Frequency Current Transformer
Split-core clamp installs on grounding leads to pick up PD high-frequency pulse currents.

04
UHF
UHF Sensor Series
300–3000 MHz response for partial discharge detection in GIS, transformers and switchgear.

The cost of silence · a fact about equipment failure
70%
THE FIGURE
of high-voltage equipment failures
trace back to this.
"Insulation degradation is never silent —
it's simply waiting for an instrument that can hear it."
Over 70% of high-voltage equipment failures stem from the long-term accumulation of partial discharge signals. Equipment does not break suddenly — its symptoms are ignored for months.

02 · Warning window
6–24 months
PD typically gives six-plus months of warning before equipment trips — if anyone is listening.
03 · Per outage
Millions NT$
Production halts, contractual penalties, equipment replacement — far costlier than monitoring.
04 · Coverage
< 1%
Most substations still rely on periodic manual inspection, not 24/7 continuous signal capture.
