Digital Meter Provides Better Accuracy Use the Hastings 6702 Digital Voltage Phase Meter to make sure you have voltage on both sides of power line switches/cutout fuses and check all the phases. With the digital readout you see the small differences in the voltage reading. Both sides of the cutout fuses should read zero volts but could possibly show 200-400 volt fluctuations. HIpot Underground Cable The purpose of hipoting underground cable is to…
Updated Requirements for Personal Protective Equipment (PPE)
Why PPE Matters More Than Ever Even with the best equipment and safe work practices, arc flash hazards remain one of the most dangerous risks electricians face. In less than a second, an arc flash can release temperatures up to 35,000°F, hot enough to melt steel, ignite non-flame-resistant clothing, or fuse fabric into the skin. That’s why the NFPA 70E: Standard for Electrical Safety in the Workplace continues to evolve-providing stricter guidance for arc…
Digital Voltage Phasing Meter Part 1 – Potential Testing, URD Cable Testing
0-40KV Digital Volt Meter for Phasing Circuits The Hastings 6702 Digital Voltage Phasing Meter consists of high voltage resistors encapsulated inside two fiberglass housings. These resistors are connected together with a coiled cord. A digital display is attached to one of the encapsulated resistor housings. Attach each encapsulated resistor to a hot stick of appropriate length for the voltages to be tested. Measures overhead and underground voltages, Potential Testing and URD Cable Testing. Circuit Potential…
Electrical Safety in the Workplace Pt 3 – The Electrical Thermographer and IR Windows
Arc Flash Hazards and the Electrical Thermographer The goal of any electrical thermographer is to prevent unplanned shutdowns in a manner that is reliable, repeatable and above all safe. Since thermographers work with the target equipment online and on load coupled with the fact that IR Cameras cannot “see” through panel covers, thermographers face severe safety hazards when attempting to scan electrical distribution equipment. Taking measurements with a cover removed is not a safe option….
Using HART Protocol to Manage for Quality – Martel LC-110H and HART Communications Diagnostics
Abstract In this white paper we are going to cover the basics on HART communications and the diagnostic capability of the Martel LC-110H mA (loop) calibrator. Exactly what is HART Communication? In today’s process plants, most new field instruments are smart digital instruments. The most common class of smart instruments incorporates the HART protocol, with more than five million HART instruments in use in 100,000 plants worldwide. HART, an…
Electrical Safety: Meeting NFPA Compliance Requirements for Arc Flash & PPE
Understanding NFPA 70E – The Benchmark for Electrical Safety Electrical hazards remain one of the most serious risks in industrial and commercial environments. The NFPA 70E Standard for Electrical Safety in the Workplace establishes the framework for protecting personnel from shock, electrocution, arc flash, and arc blast incidents. While NFPA 70E is not federal law, it provides the accepted benchmark for demonstrating compliance with OSHA’s General Duty Clause (Section 5(a)(1)), which requires employers…
