Since 1988, North Central Electric (NCE) has been a trusted leader in the electrical industry, serving the needs of utility, commercial, and industrial clients across Coatesville and beyond. Specializing in high voltage cable testing and a comprehensive range of electrical services, we are committed to delivering technical expertise, reliability, and safety in every project. For organizations that rely on uninterrupted electrical performance, our services ensure cables and systems are robust, safe, and fully compliant with industry standards.

The Importance of High Voltage Cable Testing

High voltage testing is a critical part of electrical maintenance, especially for industries that rely on consistent, high-power transmission. Over time, electrical cables experience wear and environmental stress, which can lead to insulation degradation, faults, and potential failures. Without proper testing, these issues can result in operational shutdowns, costly repairs, and safety risks. At NCE, our services identify potential faults before they escalate, ensuring your systems are reliable and your operations uninterrupted.

Through high voltage cable testing, we can evaluate the integrity of both new and in-service cables, providing precise diagnostics that enhance equipment lifespan and performance. Our technicians are equipped with state-of-the-art testing tools, allowing us to deliver advanced diagnostics that meet ANSI, IEEE, AEIC, and IEC standards. These rigorous standards ensure that our testing processes are thorough, safe, and aligned with best practices across the electrical industry.

Comprehensive Cable Testing Services

Our high voltage testing services offer clients a full range of diagnostic capabilities that support operational efficiency and safety. During testing, our engineers analyze every critical aspect of your cable systems, providing a detailed overview of their current condition. 

Here’s a look at some of the key testing methods we use:

  • VLF (Very Low Frequency) Hipot Testing up to 138 kV Cable (200 kV peak) – This is a preferred method for detecting insulation weaknesses in cables.
  • AC Resonant Hipot Testing – Ideal for high-voltage cables and useful for pinpointing insulation weaknesses.
  • DC Hipot Testing (up to 600 kVDC) – Effective for insulation testing of cables, transformers, and other high-voltage components.
  • Partial Discharge Analysis (both Offline and Online) – Helps detect and localize partial discharges, a common precursor to insulation failure.
  • Tan Delta Analysis – A measure of insulation quality and a valuable indicator of potential insulation deterioration.
  • Time Domain Reflectometry (TDR) & Fault Locating – These methods are used to detect and locate faults, improving repair efficiency and minimizing downtime.
