When surge arresters fail unexpectedly, the consequences extend far beyond equipment replacement. Ground faults cascade into widespread blackouts, affecting thousands of customers and costing utilities millions in lost revenue and emergency response. Our RCA series transforms surge arrester maintenance from reactive crisis management into proactive asset protection.
Surge arresters silently protect your electrical infrastructure every day, but their deterioration often goes unnoticed until catastrophic failure occurs. Traditional maintenance approaches miss the early warning signs that could prevent disasters. While total leakage current measurements provide basic health indicators, they lack the sensitivity to detect the resistive current increases that signal imminent failure.
The challenge lies in measurement precision. Resistive current – the true indicator of arrester deterioration – represents only 10-20% of total leakage current, typically ranging from just 10 to 600 microamperes. This tiny signal holds the key to preventing major grid failures, but conventional diagnostic methods struggle to isolate and accurately measure it.
Our RCA series employs breakthrough phase detection technology that measures resistive current without requiring voltage reference inputs. By expanding total leakage current into Fourier series at voltage zero points, the system isolates sine components that represent true resistive current with exceptional accuracy.
This innovation overcomes the field application challenges that have limited other diagnostic approaches, delivering laboratory-grade precision in portable, field-ready instruments.
The flagship model combines comprehensive analysis capabilities with optional voltage input for the most demanding diagnostic applications. Features high-resolution Super AMOLED display, octa-core processing power, and complete connectivity options including USB 3.1, Bluetooth 5.0, and Wi-Fi for seamless data integration.
IP67 environmental protection ensures reliable operation in harsh field conditions.
Optimized for routine maintenance operations, the RCA1500 delivers full resistive current analysis with wireless connectivity and professional-grade ruggedness.

According to IEC 60099-5 standards, normal surge arrester operation produces resistive leakage current between 10µA and 600µA peak. When this current increases 3-4 times the initial value, deterioration has reached critical levels requiring immediate attention.
