PH Online Monitor

Insulation Resistance Online Monitoring and Alarm DeviceOnline insulation resistance monitoring and alarm for equipment such as electric motors, engines, transformers, cables, and power capacitors. The instrument consists of a measuring circuit section and a display control section. The measuring circuit is installed in a stainless steel metal housing, with high-voltage output.LThe line and measurement circuit is first isolated by high voltage and then encapsulated as a whole. After online installation, the high voltage of the object being tested will not damage the instrument. The measurement circuit section can be installed inside the distribution box, and it features an不锈钢 metal shell design.4A fixed card slot installation; the display control section is mounted on the door of the electrical distribution cabinet.(Hole Cutting86mmx86mm)Convenient for operation and observation.

The instrument employs large-scale integrated circuits and numerous precision high-voltage electronic components, with test voltages reaching2500VOr5000VOptional Insulation Resistance Measurement Range0.01MΩ~2.5TΩ. Features liquid crystal display, data storage, data query, low insulation resistance alarm, and automatic lockout (outputs an alarm when triggered)220VControl signals to control the power supply of the tested equipment; or, when electrical equipment is in operation, lock the instrument through the auxiliary contacts of the high-voltage circuit breaker, so the instrument does not operate. When the electrical equipment is taken out of operation, the instrument automatically tests the insulation resistance of the electrical equipment. If the tested insulation resistance is不合格, the instrument sounds and lights an alarm, and the operation of high-voltage electrical equipment is not permitted. Remote Monitoring (The controller's back design features)RS485ModbusCommunication interfaces, providing protocols for secondary development, and more. The instrument also features absorption ratio and polarization index testing capabilities. It boasts high measurement accuracy, ease of operation, convenient installation, stable and reliable performance, and strong anti-interference ability. It also has shockproof, dustproof, and moisture-proof structures, making it an intelligent instrument for online insulation resistance monitoring of large-scale power equipment in the power, mining, oilfield, river and canal irrigation and drainage industries.。
