OMICRON · Primary test system
CPC 100
Primary test system for CT, VT and transformer ratio, excitation and winding resistance, plus primary injection.
Industry-leading test instruments for every diagnostic scenario.
Our laboratory holds 24 calibrated instruments from OMICRON, Megger, KoCoS, Vanguard, Sonel, HVI, B2 Electronics, Fluke, Kyoritsu, EA Technology and Chauvin Arnoux — from protection relays to partial discharge and power quality.
Owned, calibrated instruments for relay, CT/VT and circuit-breaker testing.
Primary test system for CT, VT and transformer ratio, excitation and winding resistance, plus primary injection.
Three-phase relay and substation test set for secondary injection, protection-scheme proving and trip-time measurement.
Rugged universal protection-relay test system for overcurrent, distance, differential and motor protection, indoors or out.
High-current injection through the primary circuit to prove CT polarity, protection operation and complete trip paths.
Ratio, polarity, excitation (knee-point) curve, winding resistance and burden tests on protection and metering CTs.
Timing, contact travel and coil-current analysis of MV circuit-breaker open, close and close-open operations.
High-current contact-resistance measurement on breaker main contacts, busbar joints and bolted connections.
Digital low-resistance ohmmeter with up to 200 A test current for breaker contacts, busbars and joints.

Owned, calibrated instruments for earthing, LV, live diagnostics and network analysis.
Earth-electrode resistance by fall-of-potential, soil resistivity and stakeless clamp-on measurements.
LV installation testing: insulation, continuity, loop impedance, RCD and earth tests to IEC 60364.
Partial-discharge screening of live MV switchgear and terminations using TEV and ultrasonic sensing.
Professional infrared camera for live thermographic surveys of switchgear, busbars, cables and connections.
Compact thermal imager for routine hot-spot checks during preventive-maintenance rounds.
